CSS spacing between cells problem

Hi everybody,

I’m trying to include a HTML table in a widget.

I was able to set some CSS code and currently have this output:

As you can see, a separation between rows is appearing in the output.

The correct output should be:

The code I have so far is:

May somebody help to fix this issue please?

Many thanks in advance.
