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