I have used Jtable and the table model used is DefaultTableModel(). My table has 10 columns, in which the 4th column is editable and the 7th column is editable.
My requirement is that, whenever the focus is lost from the 4th column, it should jump to the 7th column. How to use this focus traversing.
I am very much need of getting this done, i am waiting for great replies...
One more thing, i have used Double datatype for 4th column, by default 0 will get displayed, when the user edits, the value gets appended to the right side of decimal point, like 0.023, how to avoid this too.
Advance Thanks,
