<div id="cls-Ext.layout.TableLayout"></div>/**
* @class Ext.layout.TableLayout
* @extends Ext.layout.ContainerLayout
* <p>This layout allows you to easily render content into an HTML table. The total number of columns can be
* specified, and rowspan and colspan can be used to create complex layouts within the table.
* This class is intended to be extended or created via the layout:'table' {@link Ext.Container#layout} config,
* and should generally not need to be created directly via the new keyword.</p>
* <p>Note that when creating a layout via config, the layout-specific config properties must be passed in via
* the {@link Ext.Container#layoutConfig} object which will then be applied internally to the layout. In the
* case of TableLayout, the only valid layout config property is {@link #columns}. However, the items added to a
* TableLayout can supply the following table-specific config properties:</p>
* <ul>
* <li><b>rowspan</b> Applied to the table cell containing the item.</li>
* <li><b>colspan</b> Applied to the table cell containing the item.</li>
* <li><b>cellId</b> An id applied to the table cell containing the item.</li>
* <li><b>cellCls</b> A CSS class name added to the table cell containing the item.</li>
* </ul>
* <p>The basic concept of building up a TableLayout is conceptually very similar to building up a standard
* HTML table. You simply add each panel (or "cell") that you want to include along with any span attributes
* specified as the special config properties of rowspan and colspan which work exactly like their HTML counterparts.
* Rather than explicitly creating and nesting rows and columns as you would in HTML, you simply specify the
* total column count in the layoutConfig and start adding panels in their natural order from left to right,
* top to bottom. The layout will automatically figure out, based on the column count, rowspans and colspans,
* how to position each panel within the table. Just like with HTML tables, your rowspans and colspans must add
* up correctly in your overall layout or you'll end up with missing and/or extra cells! Example usage:</p>
* <pre><code>
// This code will generate a layout table that is 3 columns by 2 rows
// with some spanning included. The basic layout will be:
// +--------+-----------------+
// | A | B |
// | |--------+--------|
// | | C | D |
// +--------+--------+--------+
var table = new Ext.Panel({
title: 'Table Layout',
layout:'table',
defaults: {
// applied to each contained panel
bodyStyle:'padding:20px'
},
layoutConfig: {
// The total column count must be specified here
columns: 3
},
items: [{
html: '<p>Cell A content</p>',
rowspan: 2
},{
html: '<p>Cell B content</p>',
colspan: 2
},{
html: '<p>Cell C content</p>',
cellCls: 'highlight'
},{
html: '<p>Cell D content</p>'
}]
});
</code></pre>
