Controlling the knob of a JScrollPane

Question

I have a JTable inside a JScrollPane.
When starting the program the horizontal knob is at its left-most position.
The JTable is larger than the JViewPort, hence only the top left area of the JTable is visible.
Using the mouse pointer I can drag the horizontal knob towards the right, hence scrolling the JTable.
Now that I have manually scrolled my JTable, I want to click on the contents of one cell of the JTable and do some actions.
The problem is that, as soon as I click on the JTable, the horizontal knob moves back to its original left-most position and the JTable gets scrolled back to its left corner again.
How can I keep the horizontal knob in the position that I set manually with the mouse pointer?
in other words...
How can I keep the horizontal knob in the position where it was before clicking in the JTable ?

Answer 1

Following the sugestions given by: StanislavL and akhalil100, I have inseterd the following code when creating the JScrollPane for the first time:
          theJScrollPaneOfCandidates.setMinimumSize( new Dimension(50, 50) );
          theJScrollPaneOfCandidates.setPreferredSize( new Dimension(125, 125));
          theJScrollPaneOfCandidates.getHorizontalScrollBar().setValue(500);
          * Now I am going to test if the JScrollPane has the good Value
          int theValue = theJScrollPaneOfCandidates.getHorizontalScrollBar().getValue();
I have a breakpoint placed after the last line of code, to be able to see the contents returned by getValue().
Now this is the strange behaviour:
It works when I try to set a value =< 90, but it does not work for values larger than 90.
In more detail:
I can setValue between 0 and 90 and a get the same value from getValue.
But if a setValue larger than 90, then the getValue returns always 90.
In particular, if you see the code above, I setValue(500) and in the next line of code the getValue() method returns to me 90.
