title: How to delete border spacing in table
body: <p>I have a table, first row is like</p>
  
  <pre><code>&lt;tr&gt;
  &lt;th&gt;1&lt;/th&gt;
  &lt;th&gt;2&lt;/th&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>I put a black background to "th". Now the 1 and 2 cells have some kind of border between/separating them... I had a look in source code and I think I found something:</p>
  
  <pre><code>border-collapse: separate;
  border-spacing: 2px;
  </code></pre>
  
  <p>This CSS code is listed in source code as "user agent stylesheettable" and I couldn't enable/disable it to test if this is the problem, but I tried and added the same code but with "none" and "0" parameters but it didn't help neither...</p>
  
  <p>Can somebody help and guide me where is the border from please?</p>
