Hello! I am an Independent Advisor, I would love to help you out!
It sounds like what you want to do may be to freeze panes to lock rows to always be visible.
I'd recommend viewing this article on the subject:
https://support.office.com/en-us/article/Freeze...
The information you mainly want from the link is this:
Freeze the first column
Select View > Freeze Panes > Freeze First Column.
The faint line that appears between Column A and B shows that the first column is frozen.
Freeze the first two columns
Select the third column.
Select View > Freeze Panes > Freeze Panes.
Freeze columns and rows
Select the cell below the rows and to the right of the columns, you want to keep visible when you scroll.
Select View > Freeze Panes > Freeze Panes.
Let me know if this helps!
