How to center an object/item in the table row

You can do this by anchoring a text frame in the cell, like this.

The text is setup in a rounded frame, with 2 different paragraph styles. The top line uses a paragraph border to create the vertical line and there is a rule below for the horizontal one. Ask me if you want to get the indd file.

You can place any graphic object inside a table cell - the same way as in text outside of the table. Then you can setup a cell to center contents vertically - plus set extra margins if required. Of course would be best if there are no other texts in the same cell. 

One idea:

Couldn't you place and link an InDesign page or an exported PDF.

In this case you could do a graphic cell instead of anchoring a group of text frames or whatever to a text cell.

Hi @Adrian Tušar ,

please share a sample InDesign document.

I think, there is a way. Have some ideas, but have to test them on your individual document.
