MSHFlexGrid1合并列解决方法

MSHFlexGrid1合并列
With .MSHFlexGrid1
  Set .DataSource = Rst
  .ColWidth(0) = 200
  .ColWidth(1) = 600
  .ColWidth(2) = 600
  .MergeCells = flexMergeFree 'flexMergeRestrictColumns
  End With
  End With
现在要合并一列，目标没有实现．
请问各位大侠，目标没实现是哪个单项没有设置到位，谢谢．

[解决办法]
自由合并 
MergeCells =1
MergeRow(0) =True
MergeRow(1) =True
MergeRow(2) =True
MergeRow(3) =False
