-n option doesn't work when combined with --extend-rows

[atsalolikhin-spokeo]

Example:

[~] [py-3.9.7] $ tv -n 2 /tmp/example.csv

      tv dim: 26 x 1
      one
1     two
2     three
      … with 24 more rows
[~] [py-3.9.7] $ tv -n 2 --extend-rows /tmp/example.csv

      tv dim: 26 x 1
      one
1     two
2     three
3     four
4     five
5     one
6     two
7     three
8     four
9     five
10    one
11    two
12    three
13    four
14    five
15    one
16    two
