Hi gitarjake,
Should be (Use single quotes)
editorconstant._CreateEditingTableStyle = "<table Style='border-collapse: collapse' border='1' cellspacing='0' cellpadding='0' width='500'>";
not
editorconstant._CreateEditingTableStyle = "<table Style="border-collapse: collapse" border='1' cellspacing='0' cellpadding='0' width='500'>";
