[Yoon-Ho Choi]

Hi, All

Can I make Header with two rows

and merge two cells?

Like

Header #1 Header #2 Header #3
Header #1_1 Header #1_2 Header #2_1 Header #3_1 Header #3_2
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5
Item 1_1 Item 1_2 Item 1_3 Item 1_4 Item 1_5

If you help me I'll be very happy

Thank you

I think this example is enough for your question to getting answer :)
