something i missed here, style in PHP table row works partly!

Question

no border shows up when setting style in the table row below, inside the while loop? why? Background color setting works fine, but not this... NO BORDER SHOWS UP...

    // Build Result String
$display_table = "<table>";
while($row = mysql_fetch_array($qry_result)){

$display_table .= "<tr style='border-top-width: thin; border-top-style: solid;'>"; //  wont work here, why????? But if I set bgr color to something, the bgr color works, but not the border thing... hmmmmmm

$display_table .= "<td width='110' rowspan='2'>BILD HÄR</td>";
$display_table .= "<td width='377' height='15'>$row[headline]</td>";
$display_table .= "<td width='67' rowspan='2'>$row[insert_date]</td>";
$display_table .= "</tr>";
$display_table .= "<tr>";
$display_table .= "<td height='15'>$row[price]:-</td>";
$display_table .= "</tr>";
}

$display_table .= "</table>";
echo $display_table;

Answer 1

Rows don't have borders. Cells do. Move border-top-style: solid to the td elements within the tr.

Answer 2

css doesnt always work on the tr element because it's just a container tag, try putting a class on the tr and using the stylesheet to style it up

e.g.:

<style type="text/css">
    .myrow td
    {
        border-top:solid 1px black;
    }

</style>

<table>
    <tr class="myrow">
        <td>...

Answer 3

You can try using these styles

table {
  border-collapse:collapse;
}

td {
  border-top: 1px solid black;
}
