Hi Anderson,
With latest GAS 2.50 version, when a table is in DISPLAY ARRAY, if you do a right-click , there is no option for "copy", but if you do a Ctrl-C, it will copy the content of the current whole line.
Concerning the table in INPUT ARRAY, if you do a right-click in a table cell, you should get the browser default options, and thus the "copy" option to copy the cell content.
Let me know if this can fulfill your need.
Regards,
Guney
