Yes and no :-)
To adjust the width, use Table.Font.Width(LongestString), maybe with a
for-next loop at first to check the contents of all cells in a column,
delivering a pointer to the longest string. As far as I understand, the
Table (or Grid) has one font only, so it can be easily set this way.
Correct me if I'm wrong.
The WordWrap feature is switched on in one of my projects here, but I
cannot find where quickly. Maybe I simply switched it on in the IDE as a
default. Anyway, I'm having difficulties with the height of the line as
it is not adapted automatically (at least this is my problem in Gambas2,
I don't know how this is in Gambas3 yet).
In this context I really like your idea with the label though the way
you use it is not necessary as you have Table.Font.Width to do this:

But I could imagine it useful for wrapping the text AND find out how
many rows of text result from it, setting the Height property for the row.
