比如<td rowspan="2">microsoft</td>,rowspan是向下合并一个,加上自身就是两个
比如<td colspan="2">stephen elop</td>,colspan是向右合并
希望可以帮到你

colspan的作用是指定单元格横向跨越的行数。rowspan的作用是指定单元格纵向跨越的行数。
都是要直接加在tr th td上面的
<table border= "1 " width= "200 " >
<tr>
<td colspan="4" >ss
</td>
</tr>
<tr>
<td width= "25% "> </td>
<td width= "25% "> </td>
<td width= "25% "> </td>
<td width= "25% "> </td>
</tr>
<tr>
<td width= "25% "rowspan="2"> </td>
<td width= "25% "> </td>
<td width= "25% "> </td>
<td width= "25% "> </td>
</tr>
<tr>
<td width= "25% "> </td>
<td width= "25% " rowspan="3"> </td>
<td width= "25% "> </td>
</tr>
<tr>
<td width= "25% " colspan="2" > </td>
<td width= "25% "> </td>
</tr>
<tr>
<td width= "25% "> </td>
<td width= "25% "> </td>
<td width= "25% "> </td>
</tr>
