My partner and I sit at a table - nothing happens?

An SSD must be submitted and confirmed.
If you have done this and still nothing happens, then there are no other pairs who have submitted and confirmed an SSD .... yet.
We strongly suggest to practise in eg the Office/Coaching Room, where one has to fill in an SSD.
This has the advantage that, when you and your partner come to the club Tourney Room, no SSD needs filling it only needs to be confirmed.
