如何在三列表

Question

我在调整最后一行时遇到问题。我希望最后一行包含两个大小相同的td。

<table>
    <tr>
        <th >Monthly Savings</th><th>Monthly Savings</th><th>Monthly Savings</th>
    </tr>
    <tr>
        <td>January</td>
        <td>$100</td><td>$100</td>
    </tr>
    <tr>
        <td colspan="2">February</td>
        <td colspan="2">$80</td>
    </tr>
</table>

Answer 1

删除此colspan中的td <td colspan="2">February</td>

<td>February</td>

＆＃13;

＆＃13;

table, td{border:solid 1px red;}

＆＃13;

<table>
    <tr>
    <th >Monthly Savings</th><th>Monthly Savings</th><th>Monthly Savings</th>
    </tr>
    <tr>
    <td>January</td>
    <td>$100</td><td>$100</td>
    </tr>
    <tr>
    <td >February</td>
    <td colspan="2">$80</td>
    </tr>
    </table>
