The JTable is updating!!
Fixed by using "this.dm = new DefaultTableModel(data,columnNames);"
And update with "dm.setDataVector(data, columnNames);"
It feels so close yet my brain is so dead.
I'm considering writing the code to define what the Genes are now.
I think the gene will be the "assembly" code text file.
I think that the initial population will generate exactly 1 line of a legitimate instruction.
Perhaps in later iterations more attention will be paid to how the instructions are generated.
