JTable -user input data

Hi,
I was looking through the web about the code using Jtable .I found a lot , most of them already have data fixed using the final object []={"Mary......};

Is there anywhere the said code can be modified so that user can enter data.

Example.

I might need to have a JLabel First Name, a JTextField First Name.
User will enter the name at textfield and the name will be put in the table.

Can anyone help me,?
