24 {header: "$ Sales", width: 100, sortable: true, renderer: money},
25 {header: "Employees", width: 100, sortable: true, resizable: false}
30 * The config options listed for this class are options which may appear in each
31 * individual column definition.
32 * <br/>RooJS Fix - column id's are not sequential but use Roo.id() - fixes bugs with layouts.

35 * config objects for details.

113 * @cfg {String} dataIndex (Optional) The name of the field in the grid's {@link Roo.data.Store}'s
114 * {@link Roo.data.Record} definition from which to draw the column's value. If not
115 * specified, the column's index is used as an index into the Record's data Array.
118 * @cfg {Number} width (Optional) The initial width in pixels of the column. Using this
119 * instead of {@link Roo.grid.Grid#autoSizeColumns} is more efficient.
122 * @cfg {Boolean} sortable (Optional) True if sorting is to be allowed on this column.
123 * Defaults to the value of the {@link #defaultSortable} property.
124 * Whether local/remote sorting is used is specified in {@link Roo.data.Store#remoteSort}.
127 * @cfg {Boolean} locked (Optional) True to lock the column in place while scrolling the Grid. Defaults to false.

139 * @cfg {Function} renderer (Optional) A function used to generate HTML markup for a cell
140 * given the cell's data value. See {@link #setRenderer}. If not specified, the
141 * default renderer returns the escaped data value. If an object is returned (bootstrap only)
142 * then it is treated as a Roo Component object instance, and it is rendered after the initial row is rendered
145 * @cfg {Roo.grid.GridEditor} editor (Optional) For grid editors - returns the grid editor
