/ In WinIE 6.x, any element with a position property set to relative and is a child of /

/ Ex: parent element DIV with a class of tableContainer has an overflow property set to auto /
thead.fixedHeader tr {
position: relative

/ set THEAD element to have block level attributes. All other non-IE browsers /
/ this enables overflow to work on TBODY element. All other non-IE, non-Mozilla browsers /
