title: Jquery td cell width always 0
body: <p>i have this table created.
  This table should have same column width for the whole table.
  If the cells have different values, so the table normaly grows.
  But i want the table to have identical columns within a given table width.</p>
  
  <p>Example:
  The screen is created in 2 segments, left and right. The right segment has the table, but the width of this segment is greater than the table width. So i can calculate every column with the same width value to show this table with same column width.</p>
  
  <p>Looks like this</p>
  
  <pre><code>  Posart   |   Datum    |
  1234567890 | 1234567890 |
     1234    | 12.12.2019 |
  
  &lt;table  id="Auftragspositionen" class="standardliste" summary=""&gt;
  &lt;tr&gt;&lt;th id="Posart"&gt;Posart&lt;/th&gt;&lt;th id="Datum"&gt;Datum&lt;/th&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
  &lt;td headers="Posart"&gt;&lt;div class="left noborder"&gt;001.00&lt;br/&gt;Z &lt;br/&gt;Zeit&lt;/div&gt;&lt;/td&gt;
  &lt;td headers="Datum"&gt;&lt;div class="middle noborder"&gt;12.03.2018&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;&lt;/table&gt;
  
  And my jQuery select is this !
  
  b2=$('#Auftragspositionen');
  b2.find("tr th").children("td").each(function(i) {
          tdWidth = $(this).width();
          alert(i + 'td width is ' + $(this).tdWidth);
          });
  </code></pre>
  
  <p>My question is, that every cell td width=0 ???
  Why it is ?</p>
