'How can I get the row, column clicked in gwt table?

I have a flextable that gets populated with data from a database.

I want to get the ROW number of the clicked row.

So far I figured out only how to get the value of a particular cell in a particular row. You have to know the position and hard code it which isn't practical.

 String test =flexTable.getFlexCellFormatter().getElement(2, 2).getInnerHTML();
 System.out.println(test);

How can I create a ClickHandler to get the selected row?

//flexTable is a FlexTable object. Add a ClickHandler to it.
flexTable.addClickHandler(new ClickHandler() {
    public void onClick(ClickEvent event) {            
            //gets the index of the cell you clicked on
            int cellIndex = flexTable.getCellForEvent(event).getCellIndex();
            //gets the index of the row you clicked on
            int rowIndex = flexTable.getCellForEvent(event).getRowIndex();
            //print statements below will verify 
            System.out.println("cellIndex "+cellIndex);
            System.out.println("rowIndex "+rowIndex);
            //gets the value of the selected cell
            String test =flexTable.getFlexCellFormatter().getElement(rowIndex,cellIndex ).getInnerHTML();
            System.out.println(test);
                
        }
    });

Solution 2:[2]

The FlexTable supports row spans and column spans, allowing you to layout data in a variety of ways. I think you should use CellTable or a DataGrid or for that matter even a CellList if only single column data is being displayed. To these widgets you can add a selectionhandler to which you can achieve your goal. Refer this it has some pre coded examples.
