How can I use margin inside td in table but without using border-collapse: separate

Let say I want to make a table like this:

I can already make the example if using border-collapse: separate property but the line itself get separated like this

when I'm using border-collapse: collapse I can make the border still there but I can't make the margin itself

Can someone help me to solve this? I'm quite confused with this problem

EDIT 1

If what I want to get is not clear I hope this image can make what I want to get more clearly

currently we still in the bottom image when the border-top line still separated but what I want to get that the border-top line still attached to it

I have trying to fix your issues please check this link:demo

Basically CSS property need to update, few properties need to update to get the resolution of the design issue
