I got a small problem with .xls files. I am parsing a file. Its good completely except the merged rows using for headers(already merged in template) getting emerged after parsing & saving. I am not doing anything for that merged rows. I am just writing in below rows. Then why they are emerged????

My template is like this. Merged & center (3 rows) for each type of error.

------------------------------------------------
User Errors | Netowrk Errors | System Error    |
------------------------------------------------

After parsing its getting emerging the cells like this.

User|  |  | Netowrk |  |   | System |   |    |

I am writing the code like this. Here I am not writing anything into that rows.
