  13  * @class Roo.grid.Grid
  14  * @extends Roo.util.Observable
  15  * This class represents the primary interface of a component based grid control.
  16  * &lt;br&gt;&lt;br&gt;Usage:&lt;pre&gt;&lt;code&gt;
  17  var grid = new Roo.grid.Grid(&quot;my-container-id&quot;, {
  18      ds: myDataStore,
  19      cm: myColModel,
  20      selModel: mySelectionModel,
  21      autoSizeColumns: true,
  22      monitorWindowResize: false,
  23      trackMouseOver: true
  24  });
  25  // set any options
  26  grid.render();
  27  * &lt;/code&gt;&lt;/pre&gt;
  28  * &lt;b&gt;Common Problems:&lt;/b&gt;&lt;br/&gt;
  29  * - Grid does not resize properly when going smaller: Setting overflow hidden on the container
  30  * element will correct this&lt;br/&gt;
  31  * - If you get el.style[camel]= NaNpx or -2px or something related, be certain you have given your container element
  32  * dimensions. The grid adapts to your container's size, if your container has no size defined then the results
  33  * are unpredictable.&lt;br/&gt;
  34  * - Do not render the grid into an element with display:none. Try using visibility:hidden. Otherwise there is no way for the
  35  * grid to calculate dimensions/offsets.&lt;br/&gt;
  36   * @constructor
  37  * @param {String/HTMLElement/Roo.Element} container The element into which this grid will be rendered -
  38  * The container MUST have some type of size defined for the grid to fill. The container will be
  39  * automatically set to position relative if it isn't already.
  40  * @param {Object} config A config object that sets properties on this grid.
