No. They are not the same. For a very small sample file the results are:
a=: makenumcol fixcsv (1!:1<'sm.csv') -.'"/'
b=:'ssdndssnnnnnnnnnnnnndnns' tblcsv 1!:1 <'sm.csv'
a-:b
0
(<a:;7){a
+--++---+++----+----+----+
|qu||444|||2000|6761|-100|
+--++---+++----+----+----+
(<a:;7){b
+--++---+++----+----+----+
|qu||444|||2000|6761|_100|
+--++---+++----+----+----+
The minus sign did not get converted properly in the table/csv case.
