Using \centering or the table environment doesn't seem to change the text inside the tabular. It shouldn't be a problem the graphics with tikz or the microtype.
How can they be centered without the left margin (using up all the page horizontal space) ?

Here are the result: I would like the tabular to be centered along the page.
What I would like to see is that each tabular align center with the page, without the left margin, a true center of all the table to the page.
The 2 to 3 last tables are wider than \textwidth, so they won't align well.
