/**
 * TDataGridColumn class
 *
 * TDataGridColumn serves as the base class for the different column types of
 * the {@link TDataGrid} control.
 * TDataGridColumn defines the properties and methods that are common among
 * all datagrid column types. In particular, it initializes header and footer
 * cells according to {@link setHeaderText HeaderText} and {@link getHeaderStyle HeaderStyle}
 * {@link setFooterText FooterText} and {@link getFooterStyle FooterStyle} properties.
 * If {@link setHeaderImageUrl HeaderImageUrl} is specified, the image
 * will be displayed instead in the header cell.
 * The {@link getItemStyle ItemStyle} is applied to cells that belong to
 * non-header and -footer datagrid items.
 *
 * When the datagrid enables sorting, if the {@link setSortExpression SortExpression}
 * is not empty, the header cell will display a button (linkbutton or imagebutton)
 * that will bubble the sort command event to the datagrid.
 *
 * Since v3.1.0, TDataGridColumn has introduced two new properties {@link setHeaderRenderer HeaderRenderer}
 * and {@link setFooterRenderer FooterRenderer} which can be used to specify
 * the layout of header and footer column cells.
 * A renderer refers to a control class that is to be instantiated as a control.
 * For more details, see {@link TRepeater} and {@link TDataList}.
 *
 * Since v3.1.1, TDataGridColumn has introduced {@link setEnableCellGrouping EnableCellGrouping}.
 * If a column has this property set true, consecutive cells having the same content in this
 * column will be grouped into one cell.
 * Note, there are some limitations to cell grouping. We determine the cell content according to
 * the cell's {@link TTableCell::getText Text} property. If the text is empty and the cell has
 * some child controls, we will pick up the first control who implements {@link IDataRenderer}
 * and obtain its {@link IDataRenderer::getData Data} property.
 *
 * The following datagrid column types are provided by the framework currently,
 * - {@link TBoundColumn}, associated with a specific field in datasource and displays the corresponding data.
 * - {@link TEditCommandColumn}, displaying edit/update/cancel command buttons
 * - {@link TDropDownListColumn}, displaying a dropdown list when the item is in edit state
 * - {@link TButtonColumn}, displaying generic command buttons that may be bound to specific field in datasource.
 * - {@link THyperLinkColumn}, displaying a hyperlink that may be bound to specific field in datasource.
 * - {@link TCheckBoxColumn}, displaying a checkbox that may be bound to specific field in datasource.
 * - {@link TTemplateColumn}, displaying content based on templates.
 *
 * To create your own column class, simply override {@link initializeCell()} method,
 * which is the major logic for managing the data and presentation of cells in the column.
