Graphics, Figures & Tables ⇒ Equally spaced Columns Problem

[olegkomarov]

I can't make the the column equally spaced in this MWE (the last is off):

Code: Select all

I noticed it depends on the length of the equation in \multicolumn.
Is there a workaround to keep the equation centered and the columns containing the numbers equally equispaced (with right alignment)?

Thanks in advance

Replace your tabular with this one:

Code: Select all

\begin{tabular*}{\textwidth}{l@{} *{8}{r}@{}}

But the first column is slightly indented (same as on your example).

We may try this:

Code: Select all

\begin{tabular*}{\textwidth}{@{}l@{} *{8}{r}@{}}

But then the last column is slightly indented.

Pick your choice.

It works very nice with the quite new tabu package.

P.S.: Good minimal example.

Thanks for both answers, equally precious.

@Nikolay: I was sure I tried that solution, thanks a lot (but still do not understand the interaction between \mcolumn and @{extracolsep{\fill}}.
@Thorsten: I wish I knew about tabu! Lifesaver.
