Problem We have displayed a 2D array in a table in Part 1. Now we would like to add borders to the table as shown below:
$data = array(
array('', 'header1', 'header2', 'header3'),
array('row0', 1, 2, 3),
array('row1', 4, 5, 6));
Solution
- GtkTable itself does not provide built-in method such as the
<table border=1> statement in html to add a border to each cell.
- However, the GtkTable::attach() method allows us to attach almost any widget to each cell.
- As such, to draw a border, we simply put each cell inside a GtkFrame, and attach the GtkFrame to the table.

$window->set_size_request(400, 200);
$window->connect_simple('destroy', array('Gtk','main_quit'));
$vbox = new GtkVBox();
$window->add($vbox);
// display title
$title = new GtkLabel('Display 2D Array in Table - Part 2 (add borders)');
$title->modify_font(new PangoFontDescription("Times New Roman Italic 10"));
$title->modify_fg(Gtk::STATE_NORMAL, GdkColor::parse("#0000ff"));
$title->set_size_request(-1, 40);
$vbox->pack_start($title, 0, 0);
$table = new GtkTable();
$vbox->pack_start($table);
$data = array(
array('', 'header1', 'header2', 'header3'),
array('row0', 1, 2, 3),
array('row1', 4, 5, 6));
display_table ($table, $data);
function display_table($table, $a) {

Explanation Please refer to Part 1 first which explains how to display a 2D array in a table.
What's new here in Part 2:
- Create the frame
- Put the cell content (GtkLabel) inside the frame
- Attach the frame (not the GtkLabel) to the table
And you now have a table with borders!
