In this example we add four labels to a homogeneous table that has a padding of 5px between cells.
The interesting bits from this example are: 
- Where we set the table as homogeneous and the padding:   
- Where we add each label to the table: 
Here you can see the full source: 
#include <Elementary.h>
EAPI_MAIN int
elm_main(int argc, char **argv)
{
   Evas_Object *win, *label, *table;
   evas_object_show(table);
   elm_object_text_set(label, "label 0");
   evas_object_show(label);
   elm_object_text_set(label, "label 1");
   evas_object_show(label);
   elm_object_text_set(label, "label 2");
   evas_object_show(label);
   elm_object_text_set(label, "label 3");
   evas_object_show(label);
   evas_object_show(win);
   return 0;
}
Our example will look like this:
