The following code first creates some table data and then checks if any cell in the table is void:

service instruction_examples

   command exit_repeat_example_1
      script
      
         // create table data provider with 2 rows and 4 columns, and containing some simple test data
         const positive32 row_count = 2
         const positive32 column_count = 4
         const table_data_provider table_data_provider = fa_table_data_provider_for_tests.co_create ( &
         	i_row_count = c_row_count &
         	i_column_count = c_column_count )
         	
         // check if the table contains any void cells

         var yes_no void_cell_found = no         	
         repeat from row_index = 1 to c_row_count id: row_loop     // loop through all rows
            repeat from column_index = 1 to c_column_count         // loop through all columns
            
               if c_table_data_provider.co_cell_value ( &
                  i_row_index = v_row_index &
                  i_column_index = v_column_index ) =r void then
                  v_void_cell_found = yes
                  exit repeat row_loop
               end if

            end repeat
         end repeat
         
         if v_void_cell_found then
            //...
         end if

      end script
   end command
   
end service
