Background:

At my work, I have a number of users who use tables a lot, but the tables start out empty for the most part. They like the borders to show, so they wind up entering “nbsp's” in every empty cell.

While the non-breaking-spaces solve the problem, I think it is cumbersome way to go about it.

Twiki::emitTR says:

sub emitTR {
    my ( $pre, $cells, $insideTABLE ) = @_;
    if( $insideTABLE ) {
        $cells = "$pre TR TD  $cells";
    } else {
        $cells = "$pre TABLE border=\"1\" TR TD  $cells";
    }
    $cells =~ s@\|\s*$@ /TD  /TR @go;
    $cells =~ s@\|@ TD TD @go;
    return $cells;
}

My understanding is that entering into the function, we need to replace $pre with an “nbsp” if $pre is empty. The most difficult part for me is in the last two lines before the return. Recursive substitution?? Anyone out there knows what to do here?
