I want to insert some data from a txt-file in a table. If I use the object[][] I must know what data I have to insert there. How can I insert data to the table when I don't know how many cols I have?
Please help, thanks!

do you mean how many rows you have? if you do simply call the getRowCount() function of jtable to find out how many r already there. Jtable is dynamic and all u have to do is add an item using the addElement method from the default table model.
