# Introduction

VTable is a canvas table library based on visual rendering engine [VRender](https://github.com/VisActor/VRender). 

The core capabilities are as follows:

1. Extreme performance: Supports fast computation and rendering of millions of data points.
2. Multidimensional analysis: Automatically analyzes and presents multidimensional data.
3. Strong expressiveness: Provides flexible and powerful graphic capabilities, seamlessly integrating with charts of [VChart](https://github.com/VisActor/VChart).

# Repo Intro

This repository includes the following packages:

1. vtable: VTable components
2. vtable-docs: VTable documentation

# Usage

## Installation

[npm package](https://www.npmjs.com/package/@visactor/vtable)

```bash
// npm
npm install @visactor/vtable

// yarn
yarn add @visactor/vtable
```

## Quick Start

```javascript
import * as VTable from '@visactor/vtable';

const columns =[
    {
        "field": "Order ID",
        "caption": "Order ID",
    },
    {
        "field": "Customer ID",
        "caption": "Customer ID",
    },
    {
        "field": "Product Name",
        "caption": "Product Name",
    },
    {
        "field": "Sales",
        "caption": "Sales",
    },
    {
        "field": "Profit",
        "caption": "Profit",
    }
];

const option = {
  records:[
      {
      "Order ID": "CA-2018-156720",
      "Customer ID": "JM-15580",
      "Product Name": "Bagged Rubber Bands",
      "Sales": "3.024",
      "Profit": "-0.605"
  },
  {
      "Order ID": "CA-2018-115427",
      "Customer ID": "EB-13975",
      "Product Name": "GBC Binding covers",
      "Sales": "20.72",
      "Profit": "6.475"
  },
  ...
  ],
  columns,
  widthMode:'standard'
};
const tableInstance = new VTable.ListTable(document.getElementById(CONTAINER_ID), option);
```

## Component Layout Priority

The `componentLayoutOrder` option allows you to control the layout priority of `title` and `legend`. This affects the order in which they occupy space in the drawing area. By default, the order is `['legend', 'title']`.

To place the title above the legend, you can configure it as follows:

```javascript
const option = {
  // ...other options
  title: {
    text: 'Sales Analysis',
    orient: 'top',
    align: 'center'
  },
  legends: {
    orient: 'top',
    // ...other legend options
  },
  componentLayoutOrder: ['title', 'legend']
};

const tableInstance = new VTable.ListTable(document.getElementById(CONTAINER_ID), option);
```
