Currently the Table  uses multiple headers to try and handle XL / Medium etc... styling



 *
 * @cfg {Roo.grid.AbstractSelectionModel} sm The selection model to use (cell selection is not supported yet)

 * @cfg {Roo.grid.ColumnModel} cm[] A column for the grid.
 * 
 * @cfg {String} cls table class
 *
 *
 * @cfg {string} empty_results  Text to display for no results 
 * @cfg {boolean} striped Should the rows be alternative striped
 * @cfg {boolean} bordered Add borders to the table
 * @cfg {boolean} hover Add hover highlighting
 * @cfg {boolean} condensed Format condensed
 * @cfg {boolean} responsive default false - if this is on, columns are rendered with col-xs-4 etc. classes, otherwise columns will be sized by CSS,
 *                also adds table-responsive (see bootstrap docs for details)
 * @cfg {Boolean} loadMask (true|false) default false
 * @cfg {Boolean} footerShow (true|false) generate tfoot, default true

 * @cfg {Boolean} lazyLoad  auto load data while scrolling to the end (default false)
 * @cfg {Boolean} auto_hide_footer  auto hide footer if only one page (default false)
 * @cfg {Boolean} enableColumnResize default true if columns can be resized = needs scrollBody to be set to work (drag/drop)
 * @cfg {Boolean} disableAutoSize disable autoSize() and initCSS()
 *
 * 
 * @cfg {Number} minColumnWidth default 50 pixels minimum column width 
 * 
 * @constructor
