Defaults to the Ext.grid.GroupingView.emptyGroupText. | Column
| falseText : String The string returned by the renderer when the column value is falsy (but not undefined) (defaults to `'false'`). | BooleanColumn

If the grid is being rendered by an Ext.grid.GroupingView, this option may be used to specify the text with which to prefix the group field value in the group header line. See also groupRenderer and Ext.grid.GroupingView.showGroupName. | Column

groupRenderer : Function

Optional. If the grid is being rendered by an Ext.grid.GroupingView, this option may be used to specify the function used to format the grouping field value for display in the group header. If a `groupRenderer` is not specified, the configured `renderer` will be called; if a `renderer` is also not specified the new value of the group field will be used.

The called function (either the `groupRenderer` or `renderer`) will be passed the following parameters:

- v : Object

  The new value of the group field.

- unused : undefined

  Unused parameter.

- r : Ext.data.Record

  The Record providing the data for the row which caused group change.

- rowIndex : Number

  The row index of the Record which caused group change.

- colIndex : Number

  The column index of the group field.

- ds : Ext.data.Store

  The Store which is providing the data Model.

The function should return a string value.

Optional. If the grid is being rendered by an Ext.grid.GroupingView, this option may be used to disable the header menu item to group by the column selected. Defaults to `true`, which enables the header menu group option. Set to `false` to disable (but still show) the group option in the header menu for the column. See also `groupName`.

The header text to be used as innerHTML (html tags are accepted) to display in the Grid view. Note: to have a clickable header with no text displayed use `'&#160;'`. | Column

Defaults to `false`. A hidden column may be shown via the header row menu. If a column is never to be shown, simply do not include this column in the Column Model at all. | Column

Specify as `false` to prevent the user from hiding this column (defaults to true). To disallow column hiding globally for all columns in the grid, use Ext.grid.GridPanel.enableColumnHide instead. | Column

Optional. A name which identifies this column (defaults to the column's initial ordinal position.) The `id` is used to create a CSS class name which is applied to all table cells (including headers) in that column (in this context the `id` does not need to be unique). The class name takes the form of

    x-grid3-td-id

Header cells will also receive this class name, but will also have the class

    x-grid3-hd

So, to target header cells, use CSS selectors such as:

    .x-grid3-hd-row .x-grid3-td-id

The Ext.grid.GridPanel.autoExpandColumn grid config option references the column via this unique identifier.

Column

| menuDisabled : Boolean Optional. `true` to disable the column menu. Defaults to `false`. | Column

For an alternative to specifying a renderer see `xtype`

Optional. A renderer is an 'interceptor' method which can be used transform data (value, appearance, etc.) before it is rendered). This may be specified in either of three ways:

- A renderer function used to return HTML markup for a cell given the cell's data value.
- A string which references a property name of the Ext.util.Format class which provides a renderer function.
- An object specifying both the renderer function, and its execution scope (`this` reference) e.g.:

      {
          fn: this.gridRenderer,
          scope: this
      }

If not specified, the default renderer uses the raw data value.

For information about the renderer function (passed parameters, etc.), see Ext.grid.ColumnModel.setRenderer. An example of specifying renderer function inline:

    var companyColumn = {
       header: 'Company Name',
       dataIndex: 'company',
       renderer: function(value, metaData, record, rowIndex, colIndex, store) {
          // provide the logic depending on business rules
          // name of your own choosing to manipulate the cell depending upon
          // the data in the underlying Record object.
          if (value == 'whatever') {
              //metaData.css : String : A CSS class name to add to the TD element of the cell.
              //metaData.attr : String : An html attribute definition string to apply to
              //                         the data container element within the table
              //                         cell (e.g. 'style="color:red;"').
              metaData.css = 'name-of-css-class-you-will-define';
          }
          return value;
       }
    }

See also scope.

Column

| resizable : Boolean Optional. `false` to disable column resizing. Defaults to `true`. | Column
| scope : Object Optional. The scope (`this` reference) in which to execute the renderer. Defaults to the Column configuration object. | Column

Optional. `true` if sorting is to be allowed on this column. Defaults to the value of the `Ext.grid.ColumnModel.defaultSortable` property. Whether local/remote sorting is used is specified in `Ext.data.Store.remoteSort`. | Column

A text string to use as the column header's tooltip. If Quicktips are enabled, this value will be used as the text of the quick tip, otherwise it will be set as the header's HTML title attribute. Defaults to ''. | Column
| trueText : String The string returned by the renderer when the column value is not falsy (defaults to `'true'`). | BooleanColumn
| undefinedText : String The string returned by the renderer when the column value is undefined (defaults to `'&#160;'`). | BooleanColumn

Optional. The initial width in pixels of the column. The width of each column can also be affected if any of the following are configured:

- Ext.grid.GridPanel.`autoExpandColumn`
- Ext.grid.GridView.`forceFit`

  By specifying `forceFit:true`, non-fixed width columns will be re-proportioned (based on the relative initial widths) to fill the width of the grid so that no horizontal scrollbar is shown.

- Ext.grid.GridView.`autoFill`
- Ext.grid.GridPanel.`minColumnWidth`

Note: when the width of each column is determined, a space on the right side is reserved for the vertical scrollbar. The Ext.grid.GridView.`scrollOffset` can be modified to reduce or eliminate the reserved offset.

Column

Optional. A String which references a predefined Ext.grid.Column subclass type which is preconfigured with an appropriate `renderer` to be easily configured into a ColumnModel. The predefined Ext.grid.Column subclass types are:

- `gridcolumn` : Ext.grid.Column (Default)

- `booleancolumn` : Ext.grid.BooleanColumn

- `numbercolumn` : Ext.grid.NumberColumn

- `datecolumn` : Ext.grid.DateColumn

- `templatecolumn` : Ext.grid.TemplateColumn

Configuration properties for the specified `xtype` may be specified with the Column configuration properties, for example:

    var grid = new Ext.grid.GridPanel({
        ...
        columns: [{
            header: 'Last Updated',
            dataIndex: 'lastChange',
            width: 85,
            sortable: true,
            //renderer: Ext.util.Format.dateRenderer('m/d/Y'),
            xtype: 'datecolumn', // use xtype instead of renderer
            format: 'M/d/Y' // configuration property for Ext.grid.DateColumn
        }, {
            ...
        }]
    });
