I want to align both the numbers and the text to the left using siunitx' S column type. I tried:






   A & {Column1 symbol $\Delta$} & {Column2 symbol $\delta$} \\
     & {Column1} & {Column2} \\
   B &  -5.0 \pm 1.0 & -10.0 \pm 2.0 \\
   C &   0.0 \pm 1.0 &   5.0 \pm 2.0 \\
   D & -20.0 \pm 1.0 & -100.0 \pm 2.0 \\


Unfortunately the text and the minus' from the numbers are not in line. Aligning both to the right works fine.

You are not really giving the package enough info about your input. Does for example table-format = -2.1(1) help? –  Joseph Wright Apr 2 at 8:03
table-format = -2.1(1) works for column 2 where the numbers have two integer digits. Hence, I have to specify the format individually for each column if the number of integer digits divers. Would be nice to finally set the alignment using one general option. –  A. Groh Apr 2 at 10:21
Without pre-parsing all of the column content, it's not possible to know in advance how much space to allow for the content of a column. That's the reason that siunitx needs the information 'up front': parsing tables would require a massive change to underlying structures and is far too risking in LaTeX2e. –  Joseph Wright Apr 2 at 10:46
