Hello,
I wish to populate cells with concatenations of two adjacent ones, containing (say) “aaa” and “bbb”, respectively, but want the second one to appear italicized, thus: “aaabbb”. I see no way to specify it. However, using the menus on cells containing actual text strings, it is possible to change the attributes of a substrings, which means calc has a way to maintain style attributes down to that level.
