Deleting all the rows in a JTable

Question

I need to remove all the rows in my JTable.

I have tried both of the following:

/**
 * Removes all the rows in the table
 */
public void clearTable()         


        

Answer 1

Or if you have lots of rows but very few columns...

DefaultTableModel dtm = new DefaultTableModel();
for(int i=0;i

...replaces the old DTM with a fresh one.
