You can't sort all three columns as a single list. For that you would need
newspaper-style columns. You could use Table | Convert | Table to Text,
separating with a paragraph mark, which would put the contents of each cell
in a separate paragraph. You can then use Table | Sort to sort the
paragraphs.

I have a simple table with three columns containing straight text - a
single
word in each cell. I would like to sort the contents of across all the
columns alphbetically.

Under TableSort Columns are listed individually cannot select all
three.
Under TableSortOptions Sort Column Only is ticked & greyed out - have
not been able to unselect this option.

Any help appreciated.
