/** * The table can be used to display tabular data in a grid. * * The table is a very powerful widget. It is "virtual" in that the table * data can be of any length (e.g. hundreds of thousands of rows or more) yet * only the rows which are actually being viewed are rendered. As the user * scrolls up or down, the rendered rows are removed and the newly visible rows * are rendered in their place. Rendering a large amount of data is a very, very * slow operation, so being able to render only the visible rows has HUGE * benefits. You'll sometimes hear qx.ui.table.* referred to as simply "Table" * and sometimes as "Virtual Table". Those terms reference the same widget in * qooxdoo. * * The data supplied to (and displayed by) the Table widget can be entirely * resident in memory at the browser {@link qx.ui.table.model.Simple} or can be * fetched from a "backend" (web server) as it is needed to be displayed * {@link qx.ui.table.model.Remote} (and some can be pre-fetched too). * The data model you choose determines where and how the data is retrieved from. * {@link qx.ui.table.model.Simple} provides a simple model in which all of the * table data resides in memory at the browser; i.e. the whole data set is * resident as an array of arrays in the Simple data model. Alternatively, * {@link qx.ui.table.model.Remote} allows the data to be fetched from the * backend as it is needed. {@link qx.ui.table.model.Remote} is an abstract * class that you can extend by providing the actual communication to your * backend. * * The table is organized in columns and rows. The first row contains the * **column headers**. Column headers contain the title of the column and * allow to change its width, position (by drag and drop) and sorting. * * *Meta-columns* * * A **meta-column** combines one or more columns that should be * horizontally scrolled together. This way you can define for example * fixed columns that stay always visible on the left (or right) while the * other columns can be scrolled away. * * Take the demo http://demo.qooxdoo.org/${qxversion}/demobrowser/#table~Table.html * as example: If you make your browser window * very small (or make one of the columns very wide) so the table needs * horizontal scrolling, then the left column stays always visible. This is * because the left column is one meta-column and the other columns are in * another. * * *Model* * * The model represents the data of the grid. It is implemented by a subclass * of {@link qx.ui.table.ITableModel}. * * *Selection* * * The selection of a table is managed by {@link qx.ui.table.selection.Manager}. * * */
