Yes JTable wants the user to press enter before it takes it.
I have this in one of my programs
JTable.putClientProperty(\"terminateEditOnFocusLost\", Boolean.TRUE); //make it like excel
Now when the cell looses focus it should save it.
I have no idea how we figured that out...
I just downloaded the SwingLab widgets.
Hoping that SwingLabs will be a little more intuitive
