Unable to send as mail - the table is too wide

What causes this issue?

The total width of the table is greater than the permitted width of the
mail. You can therefore not send the list as a mail. The maximum list
width is &V1& characters.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You can reduce the width of the table by reducing the width of
individual columns in the table control. Reduce the width of one or
more columns, or hide them completely. When the table is reduced to a
size that fits in the mail structure, you can send it as a mail.
