"UVM way' to print a 2-dimensional array of int

Does UVM support printout of 2-dimensional arrays (of int in principle)?
I wanted to print it in the do_print method using an uvm_printer. However, I think it’s not possible to get a printout like:

1 2 3 4
5 6 7 8
9 8 7 6

and I can print it only manually ( using $display).

In reply to adrianf0:

Overwriting do_print allows you to print these data in any format, as 1 long row or 1 column or, or …
And in the UVM never and naver use $display. The UVM provides you with a powerful reporting mechanism. You should use this and not the simple $display.
To get the format you want to print you need 2 nested loops, 1 for the rows and 1 for the columns:

for (int i = 0; i < max_i; i++)
for (int j = 0; j < max_i; j++)
$sformatf(“some string %0d[%0d][%0d]”, x[i][j]);

Thank you for your post.
At the end I solved it like that:

...
   rand logic[7:0] Y[V_SIZE][H_SIZE];
...
   virtual function void do_print(uvm_printer printer);
      super.do_print(printer);
      printer.print_array_header("Luminance", $size(Y,1)*$size(Y,2) );
      for(int unsigned x = 0; x < $size(Y,1); x++) begin
	 string Y_string;
	 for(int unsigned y = 0; y < $size(Y,2); y++)
	   Y_string = {Y_string, $sformatf("%d ", Y[x][y])};
	 printer.print_generic($sformatf("Y[%0d][:]",x), "int", $size(Y,2), Y_string);
      end
      printer.print_array_footer($size(Y) );
   endfunction // do_print
