 This extended converter allows you to specify any theme key on the custom role that's supported for tables.
 The role must be defined under a special role name `<table>` (to avoid clashing with other role names).
-Here's an example of a custom table role named `thick` that increases the width of the table border and grid lines.

 As written, the extended converter only supports the first role on the table.
 It could be enhanced to support an arbitrary number of roles, with each successive role cascading (like CSS).
