To get the formatting correct in stats you have to change the formatting in the function.inc file for each plugin (plugins/[theplugindir]/functions.inc)
Here is an example. Look for "plugin_showstats" in each plugin functions.inc file and look for lines like this:
$retval = "<table border = '0' width='100%' cellspacing='0' cellpadding='0'>";
$retval .= "<tr><td>" . $LANG_FILEMGMT['nofiles'] . "</td>";
$retval .= "<td align='right'>" . $total_pages . " (" $total_downloads"
</td></tr></table>";
... and change them so something like this:
$retval = "<table border = '0' width='70%' cellspacing='0' cellpadding='4'>";
$retval .= "<tr><td>" . $LANG_FILEMGMT['nofiles'] . "</td>";
$retval .= "<td align='right'>" . $total_pages . " (" .$total_downloads."
</td></tr></table>";
