Bootstrap Gridview Not Showing Correct

hey, i have set up 2 test projects with the same table. In the first i use the zii widget for the table and in the other one i used bootstrap for the table and menu. It seems, that the table bootstrap has a fixed size and doesn’t adjust to the cell size. Here are the pictures.

1 pic is: zii table

2 pic is: bootstrap table

3 pic is: bootstrap table with one row

4 pic is: when i use bootstrap menu and zii table

I didn’t change anything in the code, except the dropdown in the table and using the bootstrap extension. I did’t find any similar on the internet. If further information is needed, please tell me.
