I'm not sure if this is the correct group in which to post this, but here goes.

I'm creating a spreadsheet in an ASP page where I include the meta tag so that the browser converted the data into an excel file. The Meta tag is added as follows:
Response.AddHeader("Content-Type", "application/x-msexcel")

But no matter what I do, if the user tries to sort the data I get this error:
This operation requires the merged cells to be identically sized

I see that there is a workaround of highlighting the data and unmerging the cells, but I'm not sure that my client is going to go for that solution. However I cannot figure out why it thinks the cells are merged. All cells are individual when I create the page so I'm baffled.

Is there anyone who has figured out how to get rid of this problem?

Thanks,
Velvet
