I am attempting to vertically centre a multiline cell, so far without success. In the following diagram A is fine, but B/C seem to be pushed to the top, rather than placed around the middle of the box. Also the spacing between them is larger than I would prefer:

enter image description here

The main table definition is:

    \begin{longtblr}[theme = fancy, entry=none,label=none]{
            colspec = {|l|l|Q[h,l]|},
            stretch = 0,
            columns = {colsep=1mm},
            column{1} = {leftsep=0pt},
            column{3} = {rightsep=0pt},
        }

and the multicell:

        \inst{B} &
        \R{1},\DSXB{2} &
        \SetCell[r=2]{m} \Wrap{\RSFullFull{\add}} \\*
        
        \inst{C} &
        \R{1},\DLXB{2} & 
        -- \\ \hline

(Horizontal and vertical lines added just to see the issue more clearly: will be removed)

Addendum:
Purpose of gray box in the last column is not clear. Its definition is (to my opinion) to complicated. You may consider the following solution:

  • That looks much better, many thanks. But I don't follow the whys and wherefores of the changes, I'm afraid. Might you be able to explain them to me?

  • @Ian, see addendum. It may be more clear. In both examples important changes are in longtblr preamble marked by % <---.

  • the graybox is simply a place holder for a tree of tikz instructions. For the purposes of a MWE, I should have replaced it: my bad. What does the FONT in the COLSPEC do? Is that the solution here, or the VSPAN, or are both needed? Is the change to the colseps relevant to the fix?

  • Is there any way to reduce the separation of B and C? Or should I just use a raisebox?

    Commented Nov 28, 2022 at 15:23
  • @Ian, for most of your question you can find in tabularray package better answer that I can copy/rewrite them from there. Documentation is concise and well illustrated. From colspec is obvious tha font define font in columns (\bfseries in the first column), vspan determine rows span at multi row cells. In your case define equal height of spanned rows. Why you like to reduce colsep? result is very ugly! Of course it is possible, but I will not encourage you to do this.
