[Tex/LaTex] How to center a too wide table

horizontal alignmenttables

I have a document containing a table which is slightly too wide for the page. But instead of growing to the right side only, I would like to have it centered on the page.

I have tried to use the center environment but this doesn't seem to help.

If a table (or any other horizontal box) is wider than the text (\textwidth) an overfull hbox warning is given and the content is placed anyway, which makes it run into the right margin. To avoid this and to suppress the error the content must be placed in a box with is equal or smaller than \textwidth. The \makebox macro with its two optional argument for the width and horizontal alignment can be used for this: \makebox[\textwidth][c]{<table>} will center the content. See Center figure that is wider than \textwidth and Place figures side by side, spill into outer margin were this is used for figures and further explained.

For more complicated tables, especially if they should contain verbatim material, you should use a different approach. \makebox reads the whole content as macro argument which does not allow verbatim content and is not very efficient (ok, nowadays the latter isn't really important any longer). The \Makebox macro or the Makebox environment from the realboxes can be used as an replacement. It reads the content as a box. Better would be the adjustbox macro or environment from the adjustbox package together with the center key.

\begin{adjustbox}{center}
<your table (i.e. the tabular or similar environment)>
\end{adjustbox}

Which centers the content to \linewidth (mostly identical to \textwidth) by default but also takes any other length as an optional value, e.g. center=10cm. Note that <your table> should be a tabular or equivalent environment, not a table environment.

You can now also use the tabular key of adjustbox (as first key!) to save the extra \begin{tabular} .. \end{tabular} which is then added internally.

\begin{adjustbox}{tabular=lll,center}
     a & b & c \\
     a & b & c \\
     a & b & c \\
\end{adjustbox}
