I have this code:

begin{center}

$left.% Use `left.` if don't want arrow on this side.

begin{tabular}{r r r }

toprule

 strength & region & comments \

midrule

 $H_B ll H_0$ & Landau levels \

$ H_B lessapprox H_0 $& $n$-mixing & $n$ not good\

  & $ell$-lmixing & $ell$ not good \

 $H_B ll B_0$ & Paschen-Back regime & $J$ noot good, $L$ and $S$ good \

 & Intermediate regime & $J$ and $I$ good, $F$ not good \

 & Zeeman effect & $F$ good \

 bottomrule

end{tabular}

quad

rightupdownarrow%  Use `right.` if don't want arrow on this side.

rotatebox[origin=100]{0}{Landau limit}$

caption{HAILO}

end{center}

that generates:

What I would like:

• how can I make the entries in the first column (strengh, region, comments) centred with the columns contents?




• How can I have the Landau limit text at the top right corner of the table, like I drew with the red arrow?

Thanks.

How about this, based on bigdelim and makecell? The margin for the caption was obtained by trial and error – it depends on the text of the last column.

Without use of booktabs for the table (but clines instead) and with use of tikz with a n arrow that its height is found with tests:

usepackage{amssymb}

usepackage{caption}

usepackage{multirow}

Output:

PS: Just as a start...

(Needed packages for OP's non working example:

usepackage{booktabs}

usepackage{amssymb}

usepackage{rotating}

and

usepackage{caption}

for the fix with captionof{table} instead of caption{}

)

For the $left...$ effect one needs a [c] tabular. But to align the text, one need a [t] tabular. So I measured the [t] tabular and used raisebox and rule to fake a centered object with the right size. Finally, the top baseline of the tabular is actually toprule, so I had to put the text into the second line of another tabular.
