Wrap the enum values while displaying the table structure. This helps compacting of HTML table so we don't have to scroll horizontally.
This can be achieved by a small change in PMA_extractFieldSpec function in libraries/common.lib.php
$spec_in_brackets = chop(substr($fieldspec, $first_bracket_pos + 1, (strpos($fieldspec, ')') - $first_bracket_pos - 1)));
$spec_in_brackets = str_replace("','", "', '", $spec_in_brackets); //Adds a space after , to allow wrapping
This requested feature was implemented in the repository and will be part of a future release; thanks for suggesting.
