Excel 2010 - Themes are not changing anything!

I inherited a workbook that's very plain.  Nothing.  No graphics colors, etc.
I want to apply themes but when I try to apply them nothing happens.  No change in colors, fonts or anything.
I have a feeling a predecessor modified a style or something.
How can I reset the formatting of this sheet so that themes WILL take effect?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is the workbook protected?
Edward PamiasTeam Lead RRS DeskCommented:
Check conditional formatting. There might be some rules setup that you may want to remove.

If all else fails, you can copy and paste the data to a new sheet and format that one.

I found a solution, which says you need to make your data a table. Once you make it a table you can go to themes and then make the change.

Hi Edward.
The worksheet is not protected.  I inherited the sheet from someone else.

Did you try making it a table and then try to apply themes? Or just copy the data to a new sheet and try it.
