try {
FileWriter fw = new FileWriter(file);
BufferedWriter bw = new BufferedWriter(fw);
for(int i = 0; i < jTableExport.getRowCount(); i++){//rows
for(int j = 0; j < jTableExport.getColumnCount(); j++){//columns
bw.write(jTableExport.getValueAt(i, j).toString()+" ");
}
bw.newLine();
}
bw.close();
fw.close();
