I am trying to make a table with four columns: three of the columns are to be center aligned, and one is to be aligned by decimal places ( using S[table-format=3.2]). Here is my code:

documentclass{article}

usepackage{siunitx}

usepackage{booktabs}



begin{document}



begin{tabular}{c c S[table-format=3.2] c}

toprule

multicolumn{4}{c}{SI Prefixes} \

%hline hline

midrule midrule

Prefix & Symbol & Multiplication Factor & $ldots$ in Scientific Notation \

midrule

giga & G & 1000000000 & $10^9$ \

mega & M & 1000000 & $10^6$ \ 

kilo & k & 1000 & $10^3$ \

deca & D & 10 & $10^1$ \

rowcolor{gray!20} - & - & 1 & $10^0$ \

deci & d & 0.1 & $10^{-1}$ \

centi & c & 0.01 & $10^{-2}$ \

milli & m & 0.001 & $10^{-3}$ \

micro & $mu$ & 0.000001 & $10^{-6}$ \

nano & n & 0.000000001 & $10^{-9}$ \

bottomrule

end{tabular}



end{document}

However, here is my result:

The columns are overlapping, and I cannot figure out how to fix it. I can't think of a way to set the width of the third column, as that would fix the issue, but to my understanding, you can only fix the width by doing something like p{5cm}; the S type will not allow that.

As David Carlisle has already pointed out in a comment, you must (a) change S[table-format=3.2] to S[table-format=10.9] and (b) encase the string Multiplication Factor in curly braces, to keep it from being interpreted by siunitx.

In addition, you may want to (c) write si{micro} instead of $mu$ in the second column. The text-mu and math-mu glyphs look quite different in most fonts. Finally, since you're using the siunitx package, why not (d) use the S column type for the final column as well and write e9 thru e-9 instead of $10^9$ thru $10^{-9}$?

A separate observation: the standard short form of deca (or deka) is da, not D. For sure, si{deca} (si{deka} works too...) produces da.
