How can I truncate long texts in a table using CSS?

This is a variation on the answer from @RobAgar that works well for me. I define the following CSS:

td.item-node {
   max-width: 10em;
}
div.ellipsis {
   white-space: nowrap;
   overflow: hidden;
   text-overflow: ellipsis;
}

And the HTML looks like

<td class="item-note">
   <div class="ellipsis">Really super duper long item note that will truncate</div>
</td>

This way I can specify the width on the thing I care about (the table cell) without having to repeat all the white-space, overflow CSS properties for each cell. The class on the div also makes it clear what its purpose is.

Use text-overflow: ellipsis. You will need to fix the width of the cells and prevent line wrapping:

td {
  width: 100px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

EDIT: actually this won't work. It seems you need a container div to apply the styles to:

<table>
  <tr>
    <td><div>aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div</td>
(snip)

And then:

 td div {
   width: 100px;
   white-space: nowrap;
   overflow: hidden;         
   text-overflow: ellipsis;
 }

EDIT 2 Ah there is a way, but only if you use table-layout: fixed:

table {
  table-layout: fixed;
  width: 100px;
}

td {
  white-space: nowrap;
  overflow: hidden;         /* <- this does seem to be required */
  text-overflow: ellipsis;
}

You can make truncate class for long text. See below class [This works on table td]

 .truncate {
      text-overflow: ellipsis;
      overflow: hidden;
      white-space: nowrap;
      max-width: 1px;
    }

Works for others:

.truncate {
          text-overflow: ellipsis;
          overflow: hidden;
          white-space: nowrap;
        }

2021 UPDATE - PURE CSS WORKING VERSION

The accepted answer wasn't doing the trick for me...

The ONLY way to do it without specifying a min-width is achieved by using line-clamp.

.clamp {
  overflow: hidden;
  text-overflow: ellipsis;
  display: -webkit-box;
  -webkit-box-orient: vertical;
  line-clamp: 1;
  -webkit-line-clamp: 1;
}
.clamp-2 {
  line-clamp: 2!important;
  -webkit-line-clamp: 2!important;
}
.clamp-3 {
  line-clamp: 3!important;
  -webkit-line-clamp: 3!important;
}

As IE is (Finally) dying-off, and being replaced by Edge, support is now (nearly) global at 96-ish %.

IE support can be achieved by specifying a max-height based on line-height and overflow-y: hidden.

Example

.clamp {
  overflow: hidden;
  text-overflow: ellipsis;
  display: -webkit-box;
  -webkit-box-orient: vertical;
  line-clamp: 1;
  -webkit-line-clamp: 1;
}
.clamp-2 {
  line-clamp: 2!important;
  -webkit-line-clamp: 2!important;
}
.clamp-3 {
  line-clamp: 3!important;
  -webkit-line-clamp: 3!important;
}
