How do I concat two columns?

[G1vas]

Hello,

I am having a hard time finding out how do I concat two columns? For example:
Column A:

A
1
2
3

Column B:

B
4
5
6

concated column:

C
1
2
3
4
5
6

Is this possible?

Thank you.

Yes! This is known as appending in VisiData: https://www.visidata.org/docs/join/

Open the datasets with VisiData.
Press `Shift+S` to open the Sheets sheet.
Use `s` or `t` to select the sheets to concate.
Type `&` and select `append` to concatenate the selected datasets.

I forgot to mention that both of the columns are in the same sheet. I've already managed to concat two columns from two different sheets, but I do not understand how can I join two columns that are in the same sheet:(

There might be a better way, but I would dup-sheet ("), and then treat them as key columns on two different sheets.

Thanks for your help. I will keep this question unanswered for a few days, maybe someone else has an even better solution:)
