 Owing to problems behind the scenes, in a column in which one cell is
 labelled {@Code "indent { align }"}, all the other cells have to be
 so labelled, otherwise Lout make a mess of things.  This is a problem

 What most people want is for the heading to be centred in the column, and the
 aligned entries to be centred in the column as a block, but Lout cannot
 do this.  One approximation is to make the heading cell a spanning
-cell with centring, like this:
