*.ods work around.

[bloomort]

I found that no matter what I did I could not get the style and number formatting to apply to an *.ods file I was creating. The work around is to create the file as an *.xlsx download and then open it is OOcalc and when you go save as it defaults to ods.
I hope this helps any one struggling with formatting and styling.

Most importantly I would like to thank the creators for a very fine set of classes.

Just to clarify, it's not a bug, it's just not implemented yet.
I had the same problem myself and I've implemented basic styling support (see the PR #785)

Number formatting is not implemented yet in the ODS writer, but feel free to contribute.

I guessed as much. Thanks for a great utility.
I'm not so skilled as to be able to contribute. Please keep up the good work.
