Placing a symbol before a table entry without upsetting alignment by the siunitx package

Question

In the following MWE, I use the siunitx package to align numerical entries in a table. How can I place a \sim symbol before the "6" without upsetting the alignment? Table A will compile; Table B will not.

\documentclass[oneside,11pt]{book}
\usepackage[semibold,tt=false]{libertine}
\usepackage{libertinust1math}
\usepackage[
  expansion = false ,
  tracking = smallcaps ,
  letterspace = 40 ,
  final
]{microtype}
\usepackage[font={sf,small},labelsep=quad,labelfont=sc]{caption}
\usepackage{mathtools}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
% A
\begin{table}[!h]
  \centering
  \begin{tabular}{
l
S[table-format=1.1,table-number-alignment=left,table-align-text-post=false]
}
    \toprule
    & {X}\
    \midrule
    A & 6\
    B & 0.1\
    \bottomrule
  \end{tabular}
  \caption{A}
\end{table}
% B
\begin{table}[!h]
  \centering
  \begin{tabular}{
l
S[table-format=1.1,table-number-alignment=left,table-align-text-post=false]
}
    \toprule
    & {X}\
    \midrule
    A & \sim 6\
    B & 0.1\
    \bottomrule
  \end{tabular}
  \caption{B}
\end{table}
\end{document}

To add symbols, you have the key input-symbols, but this one is a comparator, so you just have to set the table-comparator switch to true:

\documentclass[oneside,11pt]{book}
\usepackage[semibold,tt=false]{libertine}
\usepackage{libertinust1math}
\usepackage[
  expansion = false ,
  tracking = smallcaps ,
  letterspace = 40 ,
  final
]{microtype}
\usepackage[font={sf,small},labelsep=quad,labelfont=sc]{caption}
\usepackage{mathtools}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
\begin{table}[!h]
  \centering
  \begin{tabular}{
l
S[table-format=1.1,table-number-alignment=left,table-align-text-post=false, table-comparator]
}
    \toprule
    & {X}\
    \midrule
    A & \sim 6\
    B & 0.1\
    \bottomrule
  \end{tabular}
  \caption{B}
\end{table}
\end{document}

I've been reading your horoscope for the new year and it looks like it starts for you with a great event: LOTS of points and lots of happiness! AHAHAHAHAHH. – Sebastiano Jan 01 '21 at 12:29

@Sebastiano: How that? You do not draw horoscopes yourself? I'm terribly disappointed… ;o) – Bernard Jan 01 '21 at 12:47

Try the following:

\documentclass[12pt]{article}
\usepackage[semibold,tt=false]{libertine}
\usepackage{libertinust1math} 
\usepackage[expansion = false,
            tracking = smallcaps,
            letterspace = 40,
            final]  {microtype}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
    \begin{center}
  \begin{tabular}{c
                  S[input-comparators,              % <----
                    table-space-text-pre=$\sim$,    % <----
                    table-format=1.1,
                    ]

                 }
    \toprule
type    &   {X}         \
    \midrule
A       & $\sim$ 6      \
B       &        0.1    \
    \bottomrule
    \end{tabular}
\caption{A}
    \end{table}
\medskip
\medskip
however, in table is better to use
\verb+table-comparator+ instead of \verb+input-comparators+ as suggested in @Bernard's answer:
\medskip
  \begin{tabular}{c
                  S[table-format=1.1,
                    table-space-text-pre=$\sim$,
                    table-comparator]   % <----
                 }
    \toprule
type    &   {X}     \
    \midrule
A       & \sim 6    \                  % <----
B       & 0.1       \
    \bottomrule
    \end{tabular}
    \end{center}
\end{document}

In both examples result is the same:

Put the \SI{\sim 6}{} instead of \sim and it is works in pdfLaTeX. Happy new year :-). See the explanation here: How to correctly use siunitx to align number in the center of a table for number with preamble

\usepackage[font={sf,small},labelsep=quad,labelfont=sc]{caption}

Thanks. Unfortunately, the "6" no longer lines up with the "0". Is there a way to accomplish that? — Andrew, Dec 31 '20 at 22:04
@Andrew I understand the English language very bit. Use a trick :-). See \!\!\!\SI{\sim 6}{} if it is good for you without to change anything. — Sebastiano, Dec 31 '20 at 22:08
