Graphics, Figures & Tables ⇒ SIUnitX. Columns are too wide; too much white space.

[gustaf4711]

I use SIunitX to insert a space between every fifth digit when printing numbers to 15 decimals. However the table becomes much too wide, i.e. there is plenty of space between the numbers.

Could anyone please show me what I do badly?

Code: Select all

\sisetup{
       table-number-alignment = center,
       uncertainty-mode = separate,
       round-mode = places,
       round-precision = 15,
       group-digits = all,
       digit-group-size=5,
       group-separator = {\:},
       output-decimal-marker = {\hspace{1pt}.\hspace{1pt}}
      }

\begin{center}
\begin{tabular}{rSS}
 \toprule
    1   &   0.245340708300901   &     0.490921500666745 \\
    2   &   0.737473728545394   &     0.493843385272051 \\
    3   &   1.234076215395325   &     0.499920871336306 \\
    ...\\
  10   &   5.387480890011257   &     0.898591961453085 \\
\bottomrule \\
\end{tabular}
\end{center}

Please try to offer a complete minimal working example.

The values ​​of the table-number-alignment and group-digits options are the default settings.

Use the table-format option with a suitable assignment to solve the problem.

[gustaf4711]

Thank you for pointing to what I was missing. Below I have added a , hopefully, minimal working example. With the table-format=2.15 it works perfectly.

Best regards,

Some notes regarding to the a4wide package:

• obsolete packages
• l2tabu

By the way, the \\ macro after the \bottomrule command can be omitted.

[gustaf4711]

Thank you for the lists of obsolete packages as well as the l2tabu (good to train my rusty German)

I add a small modification of the table. After all it had three columns of numbers two of which shall be set in the same way.
