[Tex/LaTex] Puzzling error while using sunitx (in a tabular environment)

siunitxtables

I've been working on writing a contingency table in LaTeX (I've prepared myself for a long battle to get multi-line and multi-column cells to appear as I need).

\usepackage{booktabs}
\usepackage[detect-all]{siunitx}
\usepackage{multirow}

\begin{table}[htp]
    \centering
    \begin{tabular}{
           @{}
           l
           S[table-format=3.2]
           S[table-format=3.2]
           S[table-format=3.2]
           S[table-format=3.2]
           S[table-format=3.2]
           S[table-format=3.2]
           @{}
           }
        \toprule
        \multicolumn{7}{|c|}{Factor B} \\
        & Alpha & Beta & Gamma & Delta & Epsilon & Row Total \\    

        \midrule
        \multirow{2}{*}{Alpha} & 1 & 1 & 1 & 1 & 1 & 1 \\
        & 11.11 & 2.11 & 3.11 & 4.11 & 5.11 & \\
        \multirow{2}{*}{Beta} & 2 & 2 & 2 & 2 & 2 & 2 \\
        & 22.22 & 2.22 & 3.22 & 4.22 & 5.22 & \\
        \multirow{2}{*}{Gamma} & 3 & 3 & 3 & 3 & 3 & 3 \\
        & 33.33 & 2.33 & 3.33 & 4.33 & 5.33 & \\
        \multirow{2}{*}{Delta} & 4 & 4 & 4 & 4 & 4 & 4 \\
        & 44.44 & 2.44 & 3.44 & 4.44 & 5.44 & \\
        \multirow{2}{*}{Epsilon} & 5 & 5 & 5 & 5 & 5 & 5 \\
        & 55.55 & 2.55 & 3.55 & 4.55 & 5.55 & \\
        Column Total & 111 & 222 & 333 & 444 & 555 & 666 \\

        \bottomrule
    \end{tabular}
    \caption {Table Caption}\label{my-table}
\end{table}

I receive the following error:

! siunitx Error

(siunitx) Invalid numerical input 'e'.

For immediate help type H <return>.
 ...                                              

l.157          & Alpha & Beta &
                                Gamma & Delta & Epsilon & Row Total \\

I admit I don't understand it. The non-numerical text is in the header of the table. To see the table, replace the line

    & Alpha & Beta & Gamma & Delta & Epsilon & Row Total \\

with

    1 & 2 & 3 & 4 & 5 & 6 & 7 \\

just to allow it to render.

I'm puzzled. Why "e"?

Suggestions are very appreciated.

Thanks in advance.

Best Answer

The "e" is because siunitx is trying to parse "Delta" as a number in engineering notation (eg, 1.234E+04). Fix it by writing the headings as \multicolumn{1}{c}{Delta}, etc
