在旧版的RadGrid中，想要创建多行多列表头，需要重写GridBenDept_ItemCreated方法，在这个方法里重绘表头，比较麻烦。
在新版的RadGrid中，加入了<ColumnGroups></ColumnGroups>标记，用于设置多行多列的表头。结构规则如下：
引自RadControls_For_ASPNET_AJAX帮助文档
A MultiColumn Header can be a child of only one other multicolumn header.
A MultiColumn Header must span at least one column.
A MultiColumn Header should be defined only for a single row header per level. Hence a multicolumn header always has RowSpan=1.
A column can have as a parent only one MultiColumn Header.
Each column header can span only a single column. Hence a column header always has ColSpan=1.
A column surrounded (in order of definition) by other columns with common multi header cannot have a different multicolumn header on the same or higher row level than the columns that surround it. This rule ensures proper rendering and avoids overlapping of multicolumn headers.
下面分享一个简单的例子，aspx源文件如下：
View Code 1 <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" Culture="zh-CN" 2 CellSpacing="0"> 3 <MasterTableView> 4 <ColumnGroups> 5 <telerik:GridColumnGroup HeaderText="编制数" Name="BZCount"> 6 </telerik:GridColumnGroup> 7 <telerik:GridColumnGroup HeaderText="全年" Name="All" ParentGroupName="BZCount"> 8 </telerik:GridColumnGroup> 9 <telerik:GridColumnGroup HeaderText="Q1" Name="Q1" ParentGroupName="BZCount"> 10 </telerik:GridColumnGroup> 11 </ColumnGroups> 12 <CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings> 13 <RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column"> 14 </RowIndicatorColumn> 15 <ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column"> 16 </ExpandCollapseColumn> 17 <Columns> 18 <telerik:GridBoundColumn HeaderText="编号" DataField="No"> 19 </telerik:GridBoundColumn> 20 <telerik:GridBoundColumn HeaderText="部门名称" DataField="Name"> 21 </telerik:GridBoundColumn> 22 <telerik:GridBoundColumn HeaderText="正编" DataField="AllZB" ColumnGroupName="All" 23 UniqueName="AllZB"> 24 </telerik:GridBoundColumn> 25 <telerik:GridBoundColumn HeaderText="派遣" DataField="AllPQ" ColumnGroupName="All" 26 UniqueName="AllZB"> 27 </telerik:GridBoundColumn> 28 <telerik:GridBoundColumn HeaderText="正编" DataField="Q1ZB" ColumnGroupName="Q1" UniqueName="Q1ZB"> 29 </telerik:GridBoundColumn> 30 <telerik:GridBoundColumn HeaderText="派遣" DataField="Q1PQ" ColumnGroupName="Q1" UniqueName="Q1ZB"> 31 </telerik:GridBoundColumn> 32 </Columns> 33 <ItemStyle HorizontalAlign="Center" /> 34 <GroupHeaderItemStyle HorizontalAlign="Center" /> 35 <HeaderStyle HorizontalAlign="Center" /> 36 </MasterTableView> 37 </telerik:RadGrid>生成的表头如下图：
