Details:

When Table is called with string columns, and the '--tail' option is called
with a value more than half of the table's number of rows, it crashes with a
segmentation fault. The code below can be used to reproduce the problem:


$ cat test.txt
# Column 1: test [no, str3]
abc
def
ghi
jkl
mno
pqr

$ asttable test.txt --tail=4
Segmentation fault (core dumped)
