Right margin in table cells aligned to the right in Latex

I have the following table in Latexenter image description here

Created with this code:

\begin{table}[h]
\caption{aaaa}
\label{tab:treatments}
\centering
\scalebox{0.8}{
\begin{tabular}{l c c c}
\toprule

\tabhead{Por 1} & \tabhead{Por 3}  & \tabhead{Quantificazione log-dim} & \tabhead{cintin\'a}  \\
\midrule
A & M & 99.3\%& 5.4\\
B& A &  2.0\%& 4.6\\
C & N & 5.8\% & 4.6\\
D & N & 3.5\% & 4.26\\
E & K & 22.5\% & 3.7\\
\bottomrule\\

\end{tabular}
}
\end{table}

I would like to have the third column of percentages aligned to the right At the same time the column label is too large. If I aligned the column to the right it would and up visually weird.

In a Word table I would align the column to the right and than add a right margin to the cells. The numbers would move toward the cell center while keeping their alignment to the right.

How do I do that in Latex? How do I add a margin to the right?

Solution

  • There are a number of options you can try:

    • Original:

    • Multi-row header:

      enter image description here

    • Manual alignment of centred columns using \phantoms:

      enter image description here

    • Manual alignment of centred columns using \eqmakeboxes (from eqparbox):

      enter image description here

    • Automated alignment of centred columns using siunitx:
