Vertical alignment in tables

[leomayer]

If I follow the documentation of 1.3. Cell alignment and the definitions of Table 2.4 the vertical alignment could be set with m to be vertically centered.

The following code:

\begin{table}[!htpb]
\centering
\caption{Table Caption}
\begin{tblr}{
		colspec = {|[red3,1pt]X[l,2]|[red3,1pt]X[r]|X[r]|[red3,1pt]X[r]|X[r,m]|[red3,1pt]},
		row{1,2} = {c,azure8,font=\bfseries},
		column{1} = {purple8,font=\bfseries},
		cell{1}{1} = {r=2}{m,white}, %multirow
		cell{1}{2,4} = {c=2}{c}, % multicolumn,
	}
	\hline[1pt,blue3]
	& 2019  &      & 2020   &      \\
	\hline
	& win   & loss & win    & loss \\ 
	\hline[0.7pt]
	Aggressive   & Typography  & 15\% &   21\% & 25\% \\ 
	\hline
	Moderate     & 7.5\% & 11\% & 11.5\% & 23\% \\ 
	\hline
	Conservative & 8.5\% & 12\% & 8.24\% & 12\% \\
	\hline[1pt,blue3]
\end{tblr}
\end{table}

produces

I would have expected that the parameter X[r,m] would align the content in the middle. But as depicted the last row remains on the top. When I set m in the column with Typography this works as expected.

I would guess this is a bug but don't know if it works as designed or if the settings should be used that way.

When there is only one line in the cell, m, t, and b alignments are the same. The same is true for tabular environment.

Visually the text seems to stick to the top of the cell in any case. That's especially true if there are no pqjyg letters in the text. Is there a way to manipulate the vertical alignment?
Looking at the lines with 2019, 2020, win, loss above this is quite apparent.

[lvjr]

you can use stretch=0 to remove the default struts.

[mxa]

Cool. Actually stretch=1.5 had the desired effect

[leomayer]

Just a stupid question: is the parameter dependent on the number of lines? E.g with 3 or 4 lines the value need to be adapted?

[lvjr]

Yes, positive stretch is not fit for all cases. Therefore it would be better to use stretch=0 with a larger rowsep.
