Table

The Table 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.

In the case of Table layout, the only valid layout config properties are columns and tableAttrs. However, the items added to a layout can supply the config properties rowspan (the number of rows that the spanned cell needs to cover), colspan (the number of cells that the cell should replace) and cellCls (a CSS class name added to the table cell containing the item).

The basic concept of building up a Table layout 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 layout config 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!

Exercise

• (Re-)open your index.html and update the code creating the Ext.container.Viewport component to match the following snippet:

  layout-table.js

Ext.create('Ext.container.Viewport', {
    layout: {
        type: 'table',
        columns: 3,
        tableAttrs: {
            style: {
                width: '100%'
            }
        }
    },
    defaults: {
        bodyPadding: 15,
    },
    items: [{
        title: 'Item 1',
        rowspan: 1,
        colspan: 1,
        html: 'Content 1'
    }, {
        title: 'Item 2',
        rowspan: 1,
        colspan: 1,
        html: 'Content 2'
    }, {
        title: 'Item 3',
        rowspan: 1,
        colspan: 1,
        html: 'Content 3'
    }, {
        title: 'Item 4',
        colspan: 2,
        rowspan: 1,
        html: 'Content 4'
    }]
});
