Filling Dinamyc Arrays[][]

That makes the code lighter. No need for TableColumn this time. :sweat_smile:

Just a simple call to JTable::updateUI() instead after appending a new row to the grid container: :call_me_hand:
Docs.Oracle.com/en/java/javase/11/docs/api/java.desktop/javax/swing/JTable.html#updateUI()

Here’s the new version of “JTable Example” that dynamically appends rows instead of columns: :wink:

// Imports for creating a frame:
import javax.swing.JFrame;
import javax.swing.JScrollPane;

// Import for creating a table:
import javax.swing.JTable;

// Imports for creating the data grid:
import java.util.Vector;
import static java.util.Arrays.asList;

// Fields for holding the table and its data grid + column titles:
final Vector<Vector<Object>> grid = new Vector<Vector<Object>>();
final Vector<String> titles = new Vector<String>(asList("ID", "TYPE", "VISIBLE"));
final JTable table = new JTable(grid, titles);

void setup() {
  looping = false;

  // Creates a separate frame to display the table:
  final JFrame f = new JFrame();
  f.setSize(1200, 600);
  f.add(new JScrollPane(table));
  f.setVisible(true);
}

void draw() {
  background((color) random(#000000));
}

void mousePressed() {
  redraw = true;

  final Vector<Object> row = new Vector<Object>(titles.size()); // new row.

  row.add(frameCount - 2); // "ID"
  row.add(platformNames[(int) random(platformNames.length)]); // "TYPE"
  row.add(random(1) < .5); // "VISIBLE"

  grid.add(row); // appends new row to the data grid.
  table.updateUI(); // notifies that the table has changed & needs repainting.
