   2 the ColumnModel is used to configure how and what parts of that data will be displayed in the
   3 vertical slices (columns) of the grid. The Ext.grid.ColumnModel Class is the default implementation
   4 of a ColumnModel used by implentations of <a href="output/Ext.grid.GridPanel.html" ext:cls="Ext.grid.GridPanel">GridPanel</a>.</p>
   5 <p>Data is mapped into the store's records and then indexed into the ColumnModel using the

   8 <p>Each <a href="output/Ext.grid.Column.html" ext:cls="Ext.grid.Column">Column</a> in the grid's ColumnModel is configured with a

  10 each record in the store is indexed into the ColumnModel.</p>
  11 <p>There are two ways to initialize the ColumnModel class:</p>
  12 <p><u>Initialization Method 1: an Array</u></p>
  13 <pre><code><b>var</b> colModel = <b>new</b> Ext.grid.ColumnModel([
  14     { header: <em>"Ticker"</em>, width: 60, sortable: true},
  15     { header: <em>"Company Name"</em>, width: 150, sortable: true, id: <em>'company'</em>},
  16     { header: <em>"Market Cap."</em>, width: 100, sortable: true},
  17     { header: <em>"$ Sales"</em>, width: 100, sortable: true, renderer: money},
  18     { header: <em>"Employees"</em>, width: 100, sortable: true, resizable: false}
  19  ]);</code></pre>
  20 <p>The ColumnModel may be initialized with an Array of <a href="output/Ext.grid.Column.html" ext:cls="Ext.grid.Column">Ext.grid.Column</a> column configuration
  21 objects to define the initial layout / display of the columns in the Grid. The order of each
  22 <a href="output/Ext.grid.Column.html" ext:cls="Ext.grid.Column">Ext.grid.Column</a> column configuration object within the specified Array defines the initial
  23 order of the column display.  A Column's display may be initially hidden using the
  24 <tt><a href="output/Ext.grid.Column.html#Ext.grid.Column-hidden" ext:member="hidden" ext:cls="Ext.grid.Column">hidden</a></tt></b> config property (and then shown using the column
  25 header menu).  Fields that are not included in the ColumnModel will not be displayable at all.</p>
  26 <p>How each column in the grid correlates (maps) to the <a href="output/Ext.data.Record.html" ext:cls="Ext.data.Record">Ext.data.Record</a> field in the
  27 <a href="output/Ext.data.Store.html" ext:cls="Ext.data.Store">Store</a> the column draws its data from is configured through the
  28 <b><tt><a href="output/Ext.grid.Column.html#Ext.grid.Column-dataIndex" ext:member="dataIndex" ext:cls="Ext.grid.Column">dataIndex</a></tt></b>.  If the
  29 <b><tt><a href="output/Ext.grid.Column.html#Ext.grid.Column-dataIndex" ext:member="dataIndex" ext:cls="Ext.grid.Column">dataIndex</a></tt></b> is not explicitly defined (as shown in the
  30 example above) it will use the column configuration's index in the Array as the index.</p>
  31 <p>See <b><tt><a href="output/Ext.grid.Column.html" ext:cls="Ext.grid.Column">Ext.grid.Column</a></tt></b> for additional configuration options for each column.</p>
  32 <p><u>Initialization Method 2: an Object</u></p>
  33 <p>In order to use configuration options from <tt>Ext.grid.ColumnModel</tt>, an Object may be used to
  34 initialize the ColumnModel.  The column configuration Array will be specified in the <tt><b><a href="output/Ext.grid.ColumnModel.html#Ext.grid.ColumnModel-columns" ext:member="columns" ext:cls="Ext.grid.ColumnModel">columns</a></b></tt>

  36 for all columns, e.g.:</p><pre><code><b>var</b> colModel = <b>new</b> Ext.grid.ColumnModel({
  37     columns: [
  38         { header: <em>"Ticker"</em>, width: 60, menuDisabled: false},
  39         { header: <em>"Company Name"</em>, width: 150, id: <em>'company'</em>},
  40         { header: <em>"Market Cap."</em>},
  41         { header: <em>"$ Sales"</em>, renderer: money},
  42         { header: <em>"Employees"</em>, resizable: false}
  43     ],
  44     defaults: {
  45         sortable: true,
  46         menuDisabled: true,
  47         width: 100
  48     },
  49     listeners: {

  51             saveConfig(colIndex, hidden);
  52         }
  53     }
  54 });</code></pre>
  55 <p>In both examples above, the ability to apply a CSS class to all cells in a column (including the
  56 header) is demonstrated through the use of the <b><tt><a href="output/Ext.grid.Column.html#Ext.grid.Column-id" ext:member="id" ext:cls="Ext.grid.Column">id</a></tt></b> config
  57 option. This column could be styled by including the following css:</p><pre><code><i>//add this css *after* the core css is loaded</i>
  58 .x-grid3-td-company {
  59     color: red; <i>// entire column will have red font</i>
  60 }
  61 <i>// modify the header row only, adding an icon to the column header</i>
  62 .x-grid3-hd-company {
  63     background: transparent
  64         url(../../resources/images/icons/silk/building.png)
  65         no-repeat 3px 3px ! important;
