Java SE (Java Platform, Standard Edition)

I have a requirement. In a JTable when I double click a particular row the cells in the row should set to the width which I have provided.

The problem with my code is when I click fourth row in the table, the first row gets adjusted.

So how I need help is

only if I click the first row, the first row cell size should get adjusted not when I click fourth row.

Similarly if I give some cell width and height for fourth row cells, then when I double click the fourth row, the fourth should alone get adjusted and not the other rows.

Hope I have explained clearly.

How can it be achieved?


Please find below my code. Everything is hardcoded. So it may look messy. Please excuse.
