WPF的DataGrid怎么实现多行表头

Answer 1

默认情况下，C1FlexGrid仅有一行多表头，如何来动态的给它添加多表头？
1.添加行和列：通过FlexGrid.Columns.Add和FlexGrid.Rows.Add方法添加行和列。
2.添加多行表头：通过FlexGrid.ColumnHeaders.Rows.Add方法，在ColumnHeaders区域添加多行的表头，实现多行表头。
3.设置Caption内容：通过FlexGrid.ColumnHeaders[row, column]设置Caption内容。
4.合并：通过使用AllowMerging属性对表头进行合并。
详细的代码实现，请参考下面的博客
