How do I hide a table column in print mode? - css

Question

How do I hide an entire table column in printing mode (using JS javascript:print())?
Because I'm using Bootstrap I tried its .hidden-print class to hide the last column (Operation column) in printing mode:
<table class="table table-striped">
<thead>
<tr>
<th>No</th>
<th>Name</th>
<th class="hidden-print">Operation</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>John Smith</td>
<td class="hidden-print">
Edit
Delete
</td>
</tr>
<tr>
<td>2</td>
<td>Neo</td>
<td class="hidden-print">
Edit
Delete
</td>
</tr>
<tr>
<-- continued -->
</tr>
</tbody>
</table>
but it's only hide the column's content, displaying a column without content, when I need is it also hides TH and TD tags.
Is it possible to do this?

table,th,td {
border: 1px solid;
text-align: center;
}
table {
border-collapse: collapse;
width: 100%;
}
#media print {
table,th,td {
border: 0px
}
button {
display: none;
}
}
<table class="table table-striped">
<thead>
<tr>
<th>No</th>
<th>Name</th>
<th class="hidden-print">Operation</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>John Smith</td>
<td class="hidden-print">
Edit
Delete
</td>
</tr>
<tr>
<td>2</td>
<td>Neo</td>
<td class="hidden-print">
Edit
Delete
</td>
</tr>
<tr>
</tr>
</tbody>
</table>
<button onclick="window.print();">Print</button>

Answer 2

There are issues with adding display: none; (which is what .hidden-print does) to table rows and cells because removing them from the document flow could very easily mess up the table formatting (see this question).
What about using visibility: hidden; instead?
In your case, you could try this, if you wanted to always target the last column:
#media print {
th:last-child, td:last-child {
visibility: hidden;
}
}
