Why is word-wrap not working?

Question

My word-wrap is not working at all

<table border="1" style="width:100%">
       <thead>
          <tr>
             <th>very long word</th>
          </tr>
       </thead>
       <tbody>
          <tr>
             <td style="word-wrap:break-word;">ablkasd/123123123/agsdfasdf/asdfasdfasdf/_sdfsdfsdf{123123-14werwwer-14124124-wefweshtsdf-235232323}/3235235/dasasdfasdfasdf.bsfs</td>
          </tr>
       </tbody>
    </table>

The string is not breaking and is always in one line.

I already tried all solutions from Word Wrap not working properly but still not working

Answer 1

Although the answer has been accepted, I would like to add to the accepted answer that apart from

table td {word-wrap:break-word;}

you need to ensure that the white-space property is not set to nowrap or pre.

This can prevent your td content word-wrapping even if you apply word-wrap: break-word

If some other css styles is setting you td white-space property, you can add

table td {
word-wrap:break-word;
white-space: normal;
}

This will ensure your td content has proper word-wrapping.

Hope it helps someone!
