-each column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content.
-This class is intended to be extended or created via the layout:'column' <a href="Ext.container.Container.html#layout" rel="Ext.container.Container#layout" class="docClass">Ext.container.Container.layout</a> config,
-and should generally not need to be created directly via the new keyword.</p>
-
-
-<p>ColumnLayout does not have any direct config options (other than inherited ones), but it does support a
-specific config property of <b><tt>columnWidth</tt></b> that can be included in the config of any panel added to it. The
-layout will use the columnWidth (if present) or width of each panel during layout to determine how to size each panel.
-If width or columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).</p>
-
-
-<p>The width property is always evaluated as pixels, and must be a number greater than or equal to 1.
-The columnWidth property is always evaluated as a percentage, and must be a decimal value greater than 0 and
-less than 1 (e.g., .25).</p>
-
-
-<p>The basic rules for specifying column widths are pretty simple. The logic makes two passes through the
-set of contained panels. During the first layout pass, all panels that either have a fixed width or none
-specified (auto) are skipped, but their widths are subtracted from the overall container width. During the second
-pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages based on
-the total <b>remaining</b> container width. In other words, percentage width panels are designed to fill the space
-left over by all the fixed-width and/or auto-width panels. Because of this, while you can specify any number of columns
-with different percentages, the columnWidths must always add up to 1 (or 100%) when added together, otherwise your
-layout may not render as expected.

-Example usage:</p>
-
-
-<pre class="prettyprint"><code> // All columns are percentages -- they must add up to 1
- Ext.create('Ext.panel.Panel', {
- title: 'Column Layout - Percentage Only',
- width: 350,
- height: 250,
- layout:'column',
- items: [{
- title: 'Column 1',
- columnWidth: .25
- },{
- title: 'Column 2',
- columnWidth: .55
- },{
- title: 'Column 3',
- columnWidth: .20
- }],
- renderTo: Ext.getBody()
- });
-
-// <img class="screenshot" src="../Ext.layout.container.Column2.png" alt="Ext.layout.container.Column container layout" />
-// Mix of width and columnWidth -- all columnWidth values must add up
-// to 1. The first column will take up exactly 120px, and the last two
-// columns will fill the remaining container width.
-
- Ext.create('Ext.Panel', {
- title: 'Column Layout - Mixed',
- width: 350,
- height: 250,
- layout:'column',
- items: [{
- title: 'Column 1',
