Table column sizes

I have a small caps character style, which in the compile format I have so that nrsv gets compiled to [nrsv]{.smallcaps} by adding a prefix and a suffix in the compile format for that character style. This doesn’t work in the header (first) row of the table. The text just gets compiled to nrsv instead. Character styles do seem to be applied (i.e. the prefix and suffix) for text in the body of the table.

And I’ve got a copy of the manual project and will go through it. Thanks for the pointer to it!
