How can I select an element by name with jQuery?

Question

Have a table column I'm trying to expand and hide:

jQuery seems to hide the td elements when I select it by class but not by element's name.

For example, why does:

$(".bold").hide(); // selecting by class works
$("tcol1").hide(); // select by element name does not work

Note the HTML below, the second column has the same name for all rows. How could I create this collection using the name attribute?

<tr>    
    <td>data1</td>
    <td name="tcol1" class="bold"> data2</td>
</tr>
<tr>    
    <td>data1</td>
    <td name="tcol1" class="bold"> data2</td>
</tr>  
<tr>    
    <td>data1</td>
    <td name="tcol1" class="bold"> data2</td>
</tr>

You can use the jQuery attribute selector:

$('td[name ="tcol1"]')   // matches exactly 'tcol1'
$('td[name^="tcol"]' )   // matches those that begin with 'tcol'
$('td[name$="tcol"]' )   // matches those that end with 'tcol'
$('td[name*="tcol"]' )   // matches those that contain 'tcol'
