[Tex/LaTex] Print “< .001" in table with siunitx

siunitx

I have a table where one column are p values. p values should be formatted without leading zero, and if they are smaller than .001, they should be reported as "< .001".
Numbers should be aligned at the decimal point.

A similar question is here: siunitx: Decimal alignment with 'less than' sign

But, how can I remove the leading zero?

\documentclass{article}

%tables
\usepackage{booktabs}
\usepackage{siunitx} %align numbers by decimal point

\begin{document}

\begin{tabular}{
  S[table-format = 2]
  S[table-format = -1.2, table-space-text-post = $^{***}$]
  S[table-format = -1.2, table-space-text-post = $^{***}$]
  S[table-format = 2.2]
  S[table-format = <0.3]}

How can I correctly format the "p" column?

Best Answer

This can be done by adding add-integer-zero=false, but you have to typeset your numbers without the leading zeroes, e.g. <.001 instead of <0.001.

Note, however, that removing the leading zero is not recommended at all, siunitx adds them because it is considered good typography.

Simply remove the braces around the \color{red}25.13274123. They are not necessary, and content wrapped in braces are not considered numbers I think, hence not aligned as such.

Also, the \multicolumn is not necessary, it is enough to wrap Value in braces. The reason, as I understand it, is that the e in Value could be considered a part of an exponential number, e.g. 3e8, and siunitx will then try to align it. To protect it from alignment, wrap it in braces. This is mentioned in the manual, section 4.6 Tabular material (the last sentence starting on page 13).
