Adjust/remove the padding settings for "td" in your template.css file, padding settings there will add on to your settings in the module parameters.

Eventually you need to adjust/add td paddings for sectiontableentry - to make lists like contactlist, sectionlist etc to look ok, see example below.

tr.sectiontableentry1 td { padding: 8px 6px;}
tr.sectiontableentry2 td { padding: 8px 6px;}
