Answer 1

from http://psych.ucsc.edu/AScils/phpmyadmin/Documentation.html

$cfg['ShowBrowseComments'] boolean $cfg['ShowPropertyComments'] boolean By setting the corresponding variable to TRUE you can enable the display of column comments in Browse or Property display. In browse mode, the comments are show inside the header. In property mode, comments are displayed using a CSS-formatted dashed-line below the name of the field. The comment is shown as a tool-tip for that field.

So... It looks like the field has a comment attached to it

edit: you can read the comment using:

SHOW FULL COLUMS FROM tbl_name LIKE 'col_name';
