title: When we using the % and px for width of table's tr.Which is the high priority?
body: <p>These days I using the table to render the data from server. But there are a lot of columns.So Ishould set a fixed width to some columns. But the page is responsive,when the page show in the big screen, some columns will be responsive. I write the code as follow. I just show four columns here.</p>
  
  <pre><code> &lt;table width="100%"&gt;
        &lt;tr&gt;
          &lt;td width="100px"&gt;ID&lt;/td&gt;
          &lt;td width="100px"&gt;Publish Time&lt;/td&gt;
          &lt;td width="20%"&gt;Description&lt;/td&gt;
          &lt;td width="20%"&gt;Operation&lt;/td&gt;
       &lt;/tr&gt;
      &lt;/table&gt;
  </code></pre>
  
  <p>But I think the "100px" cann't apply the td. The result is confusing. So when we mix using the "px" and "%",the "%" is higher priority than "px".</p>
