About Merging Cells

[1506085843]

Very glad your code helped me, but I still have a little problem, your code doesn't support merging cells yet, I try to fix it on your code, but it's very difficult, I can't balance horizontal well and vertical merged cells. I would like to ask if there is a good way to solve this problem?

for example ：

<Cell ss:StyleID="s65" ss:MergeAcross="3" ss:MergeDown="2"> <Data ss:Type="String">aaaa</Data> </Cell> <Cell ss:StyleID="s65" ss:MergeAcross="4" ss:MergeDown="5"> <Data ss:Type="String">aaaa</Data> </Cell> <Cell ss:StyleID="s65" ss:MergeDown="5"> <Data ss:Type="String">aaaa</Data> </Cell> <Cell ss:StyleID="s65" ss:MergeAcross="4"> <Data ss:Type="String">aaaa</Data> </Cell>
