I am quite new to Lyx but I have a problem whose solution is impossible to find for me.
I have a table that is larger than the text column width but smaller that the entire page. I would like to center it so that is goes a bit on the page margin, but staying centered. I can't find a way, it always stays aligned with the left limit of the text, as in the following image.

I know I can resize the columns but I prefer not to shrink them any more.
Thanks in advance
