How do I set the row size of a JTable?

end user requirement is that description can be 2 to 3 lines
I am assuming you are trying to display data across multiple rows in a cell JTable
. An example I tried to show data in multiple rows inside a cell.
As @Sergii suggested using JTable.setRowHeight
to increase cell height. The cell is data column
displayed with JTextArea
.
