Answer 1

你可以用这个

table { empty-cells: hide;} 
 
td { border:1px solid orange; padding:10px 15px 10px 15px }

<table> 
 
    <tr> 
 
    <td> 
 
     <input type="radio" name="one" checked="checked" id="1" /> 
 
     <label for="1">1</label> 
 
    </td> 
 
    <td colspan="3"> 
 
     <input type="radio" name="one" id="2" /> 
 

 
     <label for="2">2</label> 
 
    </td> 
 
    </tr> 
 
    <tr> 
 
    <td></td> 
 
    <td> 
 
     <input type="radio" name="one" id="3" /> 
 

 
     <label for="3">2.1.</label> 
 
    </td> 
 
    <td> 
 
     <input type="radio" name="one" id="4" /> 
 

 
     <label for="4">2.2.</label> 
 
    </td> 
 

 
    <td> 
 
     <input type="radio" name="one" id="54" /> 
 

 
     <label for="5">2.3.</label> 
 
    </td> 
 
    </tr> 
 
</table>
