QTableWidget cell clicked

[Archa4]

I need to activate a slot when the 0, 0 cell of My table is clicked.
I tried to use

connect(table, SIGNAL(cellClicked(int,int)), this, SLOT(previousWeek()));

connect(table, SIGNAL(cellClicked(int,int)), this, SLOT(previousWeek()));

To copy to clipboard, switch view to plain text mode 

But it doesn't specify what cell needs to be clicked, so the slot is activated when any cell is clicked.
I also tried to specify the cellClicked(int,int) as cellClicked(0,0), but then i get a warning:
No such signal QTableWidget::cellClicked(0,0)

How do i solve this problem?
