Table.summary() missing output is misleading

[minhster99]

Hi

I read in a file with the following structure

 Index  |   Column Name    |  Column Type  |
--------------------------------------------
     0  |              id  |      INTEGER  |
     1  |            date  |   LOCAL_DATE  |
     2  |            time  |       STRING  |
     3  |    country_name  |       STRING  |
     4  |  state/province  |       STRING  |
     5  |      population  |      INTEGER  |
     6  |  landslide_type  |       STRING  |
     7  |         trigger  |       STRING  |
     8  |      fatalities  |      INTEGER  |

when I do a summary, I get the following

  Summary   |         id          |     date     |  time  |  country_name   |  state/province  |      population      |  landslide_type  |  trigger   |  fatalities  |

The missing value is only shown for date and it does work, I can verify there were 3 missing date values. However I also can see missing values for fatalities but it does not appear here. If I do the following

table.intColumn("fatalities").isMissing().size()  // returns > 0

I suspect that missing is not implemented on the summary() call for IntColumn types because if I simply select that single column and do a summary() on it, I get the following with no missing statistic

Column: fatalities  
 Measure   |  Value  |
----------------------
    Count  |   1690  |
      sum  |         |
     Mean  |         |
      Min  |      0  |
      Max  |    280  |
    Range  |    280  |
 Variance  |         |
 Std. Dev  |         |

Could we get that statistic filled in and for those statistics that aren't supported by the column type, could we add something like 'N/A' so that it is clear? Thanks.

ps this is a great lib. Really appreciate what you've done here!
