/** * @class Ext.layout.TableLayout * @extends Ext.layout.ContainerLayout *

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.

*

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:

* *

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:

*

// 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    |
// +--------+--------+--------+

    title: 'Table Layout',

        // applied to each contained panel

        // The total column count must be specified here
        columns: 3
    },

        rowspan: 2
    },{
        html: '<p>Cell B content</p>',
        colspan: 2
    },{
        html: '<p>Cell C content</p>',
        cellCls: 'highlight'
    },{
        html: '<p>Cell D content</p>'
    }]
