The Lua version can be removed because the line
\defineexpandable\ColumnABii {\ctxlua{context([==[\ColumnA + \ColumnB]==])}}
is only a complicated form to write
\defineexpandable\ColumnABii {30mm + 40mm}
What does happen is that context replaces \ColumnA with 30mm and \ColumnB with
40mm but nothing is calculate because the argument is a simple text string.
