How I extract specific columns and lines?

I have an excel file with a table 1442x31 and I want to extract specific columns and lines.

For Example I want to make a new table named a where I want to insert: all values from 109 until 210, from columns 3-20.

1 2 3 4 5 6 7 8
2 a b c d e f g
3 a b c d e f g
4 a b c d e f g
5 a b c d e f g
6 a b c d e f g
7 a b c d e f g
8 a b c d e f g

Let's say I want all values from 3rd column but only on lines 4,5,6,7

How do I do that?

Try

A1 = A(109:210,3:20);
