This example will arrange rectangles of different sizes(and colors) in a table. While it's possible to create the same layout we are doing here by positioning each rectangle independently, using a table makes it a lot easier, since the table will control layout of all the objects, allowing you to move, resize or hide the entire table.

We'll start with creating the table, setting it to EVAS_OBJECT_TABLE_HOMOGENEOUS_NONE to have maximum flexibility and setting its padding to 0:

   table = evas_object_table_add(d.evas);
   evas_object_table_homogeneous_set(table, EVAS_OBJECT_TABLE_HOMOGENEOUS_NONE);
   evas_object_table_padding_set(table, 0, 0);
   evas_object_resize(table, WIDTH, HEIGHT);
   evas_object_show(table);

We then create each rectangle and add it to the table:

   rect = evas_object_rectangle_add(d.evas);
   evas_object_color_set(rect, 255, 0, 0, 255);
   evas_object_size_hint_min_set(rect, 100, 50);
   evas_object_show(rect);
   evas_object_table_pack(table, rect, 1, 1, 2, 1);

   rect = evas_object_rectangle_add(d.evas);
   evas_object_color_set(rect, 0, 255, 0, 255);
   evas_object_size_hint_min_set(rect, 50, 100);
   evas_object_show(rect);
   evas_object_table_pack(table, rect, 1, 2, 1, 2);

   rect = evas_object_rectangle_add(d.evas);
   evas_object_color_set(rect, 0, 0, 255, 255);
   evas_object_size_hint_min_set(rect, 50, 50);
   evas_object_show(rect);
   evas_object_table_pack(table, rect, 2, 2, 1, 1);

   rect = evas_object_rectangle_add(d.evas);
   evas_object_color_set(rect, 255, 255, 0, 255);
   evas_object_size_hint_min_set(rect, 50, 50);
   evas_object_show(rect);
   evas_object_table_pack(table, rect, 2, 3, 1, 1);

Note:: Each rectangle has a different minimum size based on how many rows and columns it will occupy.
