I have a problem to merge cells in the first-row table. I hope someone can guide me on how to solve it. Thanks.
Below is my code:
<!DOCTYPE html>
<html>
<head>
<style>
</style>
</head>
<body>
<table style="width:100%;border: 1px solid black; " class="tabletr">
<thead>
<tr style="text-align:left;S" height="35">
<th class="control-label" style="width:1%;border: 1px solid black;text-align:center;">Bill</th>
<th style="width:7%;text-align:center;border: 1px solid black;">No.Siri Pendaftaran Komponen</th>
<th class="control-label" style="width:7%;text-align:center;border: 1px solid black;">Jenis/ Jenama/ Model </th>
<th style="width:7%;text-align:center;border: 1px solid black;">Kos(RM)</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Tempoh Jaminan</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Asal/ Tambah/ Naik Taraf/ Penggantian</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Dipasang (Tarikh)</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Dikeluarkan (Tarikh)</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Dilupus/ Dihapus Kira</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Catatan</th>
<th style="width:7%;text-align:center;border: 1px solid black;">Nama Pengawai</th>
</tr>
</thead>
</table>
</body>
</html>
My problem is how to add "Tarikh" word in the Dipasang (Tarikh) , Dikeluarkan (Tarikh), Dilupus/ Dihapus Kira top .
My expected result like below the picture:
