+/**
+ * @class Ext.ux.grid.TransformGrid
+ * @extends Ext.grid.Panel
+ * A Grid which creates itself from an existing HTML table element.
+ * @history
+ * 2007-03-01 Original version by Nige "Animal" White
+ * 2007-03-10 jvs Slightly refactored to reuse existing classes * @constructor
+ * @param {String/HTMLElement/Ext.Element} table The table element from which this grid will be created -
+ * The table MUST have some type of size defined for the grid to fill. The container will be
+ * automatically set to position relative if it isn't already.
+ * @param {Object} config A config object that sets properties on this grid and has two additional (optional)
+ * properties: fields and columns which allow for customizing data fields and columns for this grid.
