Ian Cook commented on ARROW-11705:
----------------------------------

FYI if you use {{Table$create}} it does not error but gives garbage in the 2nd... Nth rows 
{code:java}
Table$create(a=1:5, b = 42) %>% collect()
# A tibble: 5 x 2
      a         b
  <int>     <dbl>
1     1 4.20e+  1
2     2 6.94e-310
3     3 6.94e-310
4     4 6.94e-310
5     5 6.94e-310 {code}
