css - How to delete border spacing in table

Question

I have a table, first row is like

<tr>
<th>1</th>
<th>2</th>
</tr>

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:

border-collapse: separate;
border-spacing: 2px;

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...

Can somebody help and guide me where is the border from please?

Answer 1

Your table be like below by default and set the css rules on tables ID or Class

<table border="0" cellspacing="0" cellpadding="0">
 <tr>
  <th>1</th>
  <th>2</th>
</tr>
</table>

css:

border-collapse: collapse;
