## Getting Started
### Install manually using `<script>` tags
To use this library, include the [FileSaver.js](https://github.com/clarketm/FileSaver.js/) library, and [TableExport](https://tableexport.travismclarke.com) library before the closing `<body>` tag of your HTML document:
```html
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
```
### Install with Bower
```shell
$ bower install tableexport.js
```
### Install with npm
```shell
$ npm install tableexport
```

### Dependencies
#### Required:
* [FileSaver.js](https://github.com/clarketm/FileSaver.js/)
#### Optional:
* [jQuery](https://jquery.com) (1.2.1 or higher)
* [Bootstrap](http://getbootstrap.com/getting-started/#download) (3.1.0 or higher)
#### Add-Ons:
In order to provide **Office Open XML SpreadsheetML Format ( `.xlsx` )** support, you must include the following third-party library in your project before both [FileSaver.js](https://github.com/clarketm/FileSaver.js/) and [TableExport](https://tableexport.travismclarke.com).
* [xlsx.core.js](https://github.com/SheetJS/js-xlsx) by _SheetJS_
> Including `xlsx.core.js` is **NOT** necessary if installing with [`Bower`](#install-with-bower) or [`npm`](#install-with-npm)
```html
<script src="xlsx.core.js"></script>
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
```
#### Older Browsers:
To support legacy browsers ( **Chrome** < 20, **Firefox** < 13, **Opera** < 12.10, **IE** < 10, __Safari__ < 6 ) include the [Blob.js](https://github.com/clarketm/Blob.js/) polyfill before the [FileSaver.js](https://github.com/clarketm/FileSaver.js/) script.
* [Blob.js](https://github.com/clarketm/Blob.js) by _eligrey_ (forked by _clarketm_)
> Including `Blob.js` is **NOT** necessary if installing with [`Bower`](#install-with-bower) or [`npm`](#install-with-npm)
```html
<script src="Blob.js"></script>
<script src="FileSaver.js"></script>
...
<script src="tableexport.js"></script>
```
## Usage
### JavaScript
To use this library, simple call the [`TableExport`](https://tableexport.travismclarke.com) constructor:
```js
new TableExport(document.getElementsByTagName("table"));
// OR simply
TableExport(document.getElementsByTagName("table"));
// OR using jQuery
$("table").tableExport();
```
Additional properties can be passed-in to customize the look and feel of your tables, buttons, and exported data.
Notice that by default, TableExport will create export buttons for three different filetypes *`xls`, `csv`, `txt`*. You can choose which buttons to generate by setting the `formats` property to the filetype(s) of your choice.
```js
/* Defaults */
TableExport(document.getElementsByTagName("table"), {
headers: true, // (Boolean), display table headers (th or td elements) in the <thead>, (default: true)
footers: true, // (Boolean), display table footers (th or td elements) in the <tfoot>, (default: false)
formats: ['xlsx', 'csv', 'txt'], // (String[]), filetype(s) for the export, (default: ['xlsx', 'csv', 'txt'])
filename: 'id', // (id, String), filename for the downloaded file, (default: 'id')
bootstrap: false, // (Boolean), style buttons using bootstrap, (default: true)
exportButtons: true, // (Boolean), automatically generate the built-in export buttons for each of the specified formats (default: true)
position: 'bottom', // (top, bottom), position of the caption element relative to table, (default: 'bottom')
ignoreRows: null, // (Number, Number[]), row indices to exclude from the exported file(s) (default: null)
ignoreCols: null, // (Number, Number[]), column indices to exclude from the exported file(s) (default: null)
trimWhitespace: true, // (Boolean), remove all leading/trailing newlines, spaces, and tabs from cell text in the exported file(s) (default: false)
RTL: false, // (Boolean), set direction of the worksheet to right-to-left (default: false)
sheetname: "id" // (id, String), sheet name for the exported spreadsheet, (default: 'id')
});
```
> **Note:** to use the `xlsx` filetype, you must include [js-xlsx](https://github.com/SheetJS/js-xlsx/blob/master/dist/xlsx.core.min.js); reference the [`Add-Ons`](#add-ons) section.

### Methods
TableExport supports additional methods (**getExportData**, **update**, **reset** and **remove**) to control the [`TableExport`](https://tableexport.travismclarke.com) instance after creation.
```js
/* First, call the `TableExport` constructor and save the return instance to a variable */
var table = TableExport(document.getElementById("export-buttons-table"));
```
#### [`getExportData`](https://tableexport.v3.travismclarke.com/examples/exportButtons.html)
```js
/* get export data */
var exportData = table.getExportData(); // useful for creating custom export buttons, i.e. when (exportButtons: false)
/*****************
** exportData ***
*****************
{
"export-buttons-table": {
xls: {
data: "...",
fileExtension: ".xls",
filename: "export-buttons-table",
mimeType: "application/vnd.ms-excel"
},
...
}
};
*/
```
#### [`getFileSize`](https://tableexport.v3.travismclarke.com/examples/exportButtons.html)
```js
var tableId = 'export-buttons-table';
var XLS = table.CONSTANTS.FORMAT.XLS;
/* get export data (see `getExportData` above) */
var exportDataXLS = table.getExportData()[tableId][XLS];
/* get file size (bytes) */
var bytesXLS = table.getFileSize(exportDataXLS.data, exportDataXLS.fileExtension);
/**********************************
** bytesXLS (file size in bytes)
**********************************
352
*/
```
#### [`update`](https://tableexport.v3.travismclarke.com/examples/update_reset_remove.html)
```js
/* update */
table.update({
filename: "newFile" // pass in a new set of properties
});
```
#### [`reset`](https://tableexport.v3.travismclarke.com/examples/update_reset_remove.html)
```js
/* reset */
table.reset(); // useful for a dynamically altered table
```
#### [`remove`](https://tableexport.v3.travismclarke.com/examples/update_reset_remove.html)
```js
/* remove */
table.remove(); // removes caption and buttons
```
### Settings
Below are some of the popular configurable settings to customize the functionality of the library.
#### [`ignoreCSS`](https://tableexport.v3.travismclarke.com/examples/ignore-row-cols-cells.html)
```js
/**
* CSS selector or selector[] to exclude/remove cells (<td> or <th>) from the exported file(s).
* @type {selector|selector[]}
* @memberof TableExport.prototype
*/
// selector
TableExport.prototype.ignoreCSS = ".tableexport-ignore";
// selector[]
TableExport.prototype.ignoreCSS = [".tableexport-ignore", ".other-ignore-class"];
// OR using jQuery
// selector
$.fn.tableExport.ignoreCSS = ".tableexport-ignore" ;
// selector[]
$.fn.tableExport.ignoreCSS = [".tableexport-ignore", ".other-ignore-class"] ;
```
#### [`emptyCSS`](https://tableexport.v3.travismclarke.com/examples/ignore-row-cols-cells.html)
```js
/**
* CSS selector or selector[] to replace cells (<td> or <th>) with an empty string in the exported file(s).
* @type {selector|selector[]}
* @memberof TableExport.prototype
*/
// selector
TableExport.prototype.emptyCSS = ".tableexport-empty";
// selector[]
TableExport.prototype.emptyCSS = [".tableexport-empty", ".other-empty-class"];
// OR using jQuery
// selector
$.fn.tableExport.emptyCSS = ".tableexport-empty" ;
// selector[]
$.fn.tableExport.emptyCSS = [".tableexport-empty", ".other-empty-class"];
```
```js
/* default charset encoding (UTF-8) */
TableExport.prototype.charset = "charset=utf-8";
/* default `filename` property if "id" attribute is unset */
TableExport.prototype.defaultFilename = "myDownload";
/* default class to style buttons when not using Bootstrap or the built-in export buttons, i.e. when (`bootstrap: false` & `exportButtons: true`) */
TableExport.prototype.defaultButton = "button-default";
/* Bootstrap classes used to style and position the export button, i.e. when (`bootstrap: true` & `exportButtons: true`) */
TableExport.prototype.bootstrapConfig = ["btn", "btn-default", "btn-toolbar"];
/* row delimeter used in all filetypes */
TableExport.prototype.rowDel = "\r\n";
```
```js
/**
* Format-specific configuration (default class, content, mimeType, etc.)
* @memberof TableExport.prototype
*/
formatConfig: {
/**
* XLSX (Open XML spreadsheet) file extension configuration
* @memberof TableExport.prototype
*/
xlsx: {
defaultClass: 'xlsx',
buttonContent: 'Export to xlsx',
mimeType: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',

xls: {
defaultClass: 'xls',
buttonContent: 'Export to xls',
separator: '\t',
mimeType: 'application/vnd.ms-excel',
fileExtension: '.xls',
enforceStrictRFC4180: false
},
/**
* CSV (Comma Separated Values) file extension configuration
* @memberof TableExport.prototype
*/
csv: {
defaultClass: 'csv',
buttonContent: 'Export to csv',
separator: ',',
mimeType: 'text/csv',
fileExtension: '.csv',
enforceStrictRFC4180: true
},
/**

* @memberof TableExport.prototype
*/
txt: {
defaultClass: 'txt',
buttonContent: 'Export to txt',
separator: ' ',
mimeType: 'text/plain',
fileExtension: '.txt',
enforceStrictRFC4180: true
}
},
//////////////////////////////////////////
// Configuration override example
//////////////////////////////////////////
/* Change the CSV (Comma Separated Values) `mimeType` to "application/csv" */
TableExport.prototype.formatConfig.xlsx.mimeType = "application/csv"
```
### CSS
[TableExport](https://tableexport.travismclarke.com) packages with customized [Bootstrap](http://getbootstrap.com/getting-started/#download) CSS stylesheets to deliver enhanced table and button styling. These styles can be *enabled* by initializing with the `bootstrap` property set to `true`.
```js
TableExport(document.getElementsByTagName("table"), {
bootstrap: true
});
```
When used alongside Bootstrap, there are four custom classes **`.xlsx`, `.xls`, `.csv`, `.txt`** providing button styling for each of the exportable filetypes.

### Going Forward
#### TODOs
- [x] Update JSDocs and TypScript definition file.
- [x] Fix bug with **CSV** and **TXT** `ignoreRows` and `ignoreCols` (rows/cols rendered as empty strings rather than being *removed*).
- [x] Reimplement and test the `update`, `reset`, and `remove` **TableExport** prototype properties without requiring jQuery.
- [x] Make jQuery as *peer dependency* and ensure proper **TableExport** rendering in browser, AMD, and CommonJS environments.
- [x] Force jQuery to be an optionally loaded module.
- [x] Use the enhanced [SheetJS](https://github.com/SheetJS/js-xlsx#supported-output-formats) `xls`, `csv`, and `txt` formats (exposed via `enforceStrictRFC4180` prototype property).
- [x] Allow `ignoreCSS` and `emptyCSS` to work with any `selector|selector[]` instead of solely a single CSS class.
- [x] Ensure (via testing) full consistency and backwards-compatibility for jQuery.
- [ ] Add **Export as PDF** support.
