What does "expand data frame" mean?

Question

Data storage

Hello!
I've been instructed to "deploy data frame data by campaign", but I have absolutely no idea what that means. Isn't what is presented below a Data frame? All I found is that the data can be rotated. Is it the same thing (reversal and data rotation)? Or the data needs to be disclosed somehow and something done with it.
The initial data looks like this:
ID CAMPAIGN MEDIUM SOURCE
1 Target Ref Direct
2 Ref NULL N/A
3 Target Post Target
As I understand it, if you rotate, it will be like this (or not?):
ID 1 2 3
CAMPAIGN Target Ref Target
MEDIUM Ref NULL Post
SOURCE Direct N/A Target
Please indicate in which direction I should think!

If you do not understand what it means to "deploy a dataframe" maybe you are working in the wrong area?
This is one of the basic tasks in analytics, data engineering
