Unintended spaces in tables

Hello,

I'm facing "issue" when using tables.
In WYSYWIG editor, I have an unintended space before the text I enter in the cells.
The problem is that when I export it into excel I still have those spaces.
Sometimes, I need to transform the .xls files in .csv ones in order to import them into Loopfuse (XWiki SAS emailing campaign manager software. In this software a space is considered as a character so the emails I enter are wrong ones.
To get rid of the space, I use Notepad++, but I think it would be great to avoid it by default.

After a little enquiry, it seems that space is put there, because a few years ago, some browsers didn't allowed you to put text in a cell if there was no space there and it remained like that.

Maybe you could check if current browsers still need that space ?

Thank you
