Question

really do? I tried to find the answer but yet couldn't find! pls anyone help me

Answer 1

The Property border-collapse sets if the borders of the table are collapsed into a single border or if they are detached.
border-collapse:separate = the borders are detached. This is the Default. It means that if there is border spacing and empty cells they will not be ignored.
