Hi all,

Attached is an example showing my misunderstanding about grid alignment. The attached works as expected when \setuplayout[grid=no] is used or the 'Author table' is commented out.   The inclusion of the little table in the text is really just to convince myself that I can have a table with the grid enabled.

Any and all suggestions are greatly appreciated.

Cheers,
Randall
