------ Solution ---------------------------------------- ----
supplement, the above is just the thing to set the trigger even edit
1. settings edit attributes
2. Right pop up a menu, and then there is action triggers a signal, connect a groove
slot function example
void TableWidget :: editTableWidgetItem ()
{
TableWidget-> editItem (rightClickedItem);
}

This rightClickedItem, such judgments:
Right determine whether it is an item on the pop-up menu if you do not do not.
If you write down the words on this rightClickedItem
