Decoration of the text, provided that the visibility = true

It seems to me to be fairly simple, but never manages to decorate the text modes, under some conditions the visibility of a detail table

following pi开发者_如何学Pythoncture: A view of where the visibility is set

So, the problem would have solved if I could write: =IIF(table1.nameOfDetailRow.visibility = true, "none", "underline")

How to solve this problem?

A workaround:

* Add a second row to the group.
* Set the top border to single, the rest to none
* Set the visibility to hidden.
* Set the height to 0
* Set it to expand/collapse like the detail.

By doing the steps above, the second row will be hidden like the detail and expand with it.

When it is expanded it will show the top border, which will look like an underline (continued)
