I use Excel Writer (Cross platform) to dump table into an excel file. It works. But when i open the file the excel complains for each cell that "The number in this cell is formatted as text or preceded by an apostrophe.". It is not a very big issue but it is really annoying. I am sure that the data in the pp are real number. Is there any way to git rid of it?

And another question. Can we dump chart into excel. Or can we use an excel templates so the dumpped data will draw a plot automaticlly in excel?

Thank you.
