Create a frequency table with the available number

I make a frequency table of an array using the below command

tabulate([1 2 4 4 3 4 7])

The result is as below

Value    Count   Percent
      1        1     14.29%
      2        1     14.29%
      3        1     14.29%
      4        3     42.86%
      5        0      0.00%
      6        0      0.00%
      7        1     14.29%

How can I make a frequency table WITH ONLY available value. I just want this result

Value    Count   Percent
      1        1     14.29%
      2        1     14.29%
      3        1     14.29%
      4        3     42.86%
      7        1     14.29%
