Break the table straddle rules (borders)
Often we're receiving the feedback from our internal clients that table rule to be splitted whenever the tables are having multiple heads (attached the screen shot). Currently we unable to achieve this, need to fix in InDesign to fix this feedback.

At the moment you can give this effect by adding a narrow column where you want the break and removing the strokes where desired.
One way to program this, I suppose, would be to have the indents of the cells affect the strokes.
