Hi,
thanks for your question.
You can already set the alignment through CSS, and I feel that this is a lot more powerful than any additional settings for this – which would also make the user interface more complicated.
And of course you can restrict the “Custom CSS” code to a specific table.
Just change the selector from
.wp-table-reloaded
to
.wp-table-reloaded-id-123
(where 123 would be the ID of the table in question).
More on the CSS selectors can be found in the documentation at https://tobias.baethge.com/wordpress-plugins/wp-table-reloaded-english/documentation/
Best wishes,
Tobias
