Voici un petit passage de code tres simpliste :
<page backcolor="#ffffff" backleft="5mm" backright="5mm" backtop="10mm" backbottom="10mm" >
<page backcolor="#ffffff" backleft="5mm" backright="5mm" backtop="10mm" backbottom="10mm" >
<table border="1" cellspacing="0" cellpadding="0" style="border-collapse:collapse;width:100%;" >
<tr >
<td style="width:25%;" rowspan="3">a</td>
<td style="width:25%;">b</td>
<td style="width:25%;" rowspan="3">c</td>
<td style="width:25%;">d</td>
</tr>
<tr>
<td style="width:25%;" >e</td>
<td style="width:25%;" >f</td>
</tr>
<tr>
<td style="width:25%;" >g</td>
<td style="width:25%;" >h</td>
</tr>
</table>
<br/><br/>
<table width="100%" border="1" cellspacing="0" cellpadding="0" style="border-collapse:collapse;" >
<tr >
<td style="width:25%;" >a</td>
<td style="width:25%;" rowspan="3">b</td>
<td style="width:25%;" >c</td>
<td style="width:25%;" rowspan="3">d</td>
</tr>
<tr>
<td style="width:25%;" >e</td>
<td style="width:25%;" >f</td>
</tr>
<tr>
<td style="width:25%;" >g</td>
<td style="width:25%;" >h</td>
</tr>
</table>
</page>
</page>
Je ne comprends pas pourquoi lorsque que le premier td est en rowspan il crée une sorte de double bordure à partir du 2ieme element "rowspané"

Si quelqu'un aurai une idée je suis preneur
Merci d'avance
