Create a diffrent table in html : I want to create a table with less rows but with large columns where every 4th column right boundary is 2times thick of other boundary.
Example:
```
|  |  |  |  ||  |  |  |  ||  |  |  |  ||  |  |  |  ||
|  |  |  |  ||  |  |  |  ||  |  |  |  ||  |  |  |  ||
|  |  |  |  ||  |  |  |  ||  |  |  |  ||  |  |  |  ||
```
consider "||" as double width of "|"
