How to filter a csv file using fzf?

[gluiz1]

Take the following csv file:

Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4

I want to use fzf to filter the first column, i.e., fzf will search the following results:

Column 1
Column 1
Column 1
Column 1
Column 1
Column 1
Column 1

But, when I press enter (finish the search), I want fzf to output the entire line. For example, if [x] marks the selected Column 1 item:

Column 1
Column 1
[x] Column 1
Column 1
Column 1
Column 1
Column 1

I want the output to be the entire line from the selected value Column 1:

Column 1 [x], Column 2, Column 3, Column 4

Which other tool I need to integrate to fzf to archive this?

--with-nth:

fzf --delimiter ', ' --with-nth '{1}' << 'EOF'
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
EOF

Another option is to use --nth to limit the search scope:

fzf --delimiter ', ' --nth 1 --color nth:regular,fg:dim << 'EOF'
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
Column 1, Column 2, Column 3, Column 4
EOF
