While you can create a data table with a complex column and you can manipulate tit, it doesn't work with expressions in i or in by.

library(data.table)
packageVersion("data.table")
#> [1] '1.10.5'

dt <- data.table(y = 1, x = complex(1, 1, 1))

dt[y == 1, x := x*0]
#> Error in `[.data.table`(dt, y == 1, `:=`(x, x * 0)): Unsupported type 'complex'
dt
#>    y    x
#> 1: 1 1+1i

dt[, x, by = y]
#> Error in `[.data.table`(dt, , x, by = y): Type 15 in .SD column 0

dt[, x := x*0]
dt
#>    y    x
#> 1: 1 0+0i
