Fill a table top to bottom left to right

[ghost]

Here's what I currently have:

def show_grades(grades):
    table = Table(title="[info]<not relevant>", caption=f"[text]{args.u} @ [info]{args.y}", box=box.SQUARE, show_footer=False)
    for i in grades:
            subject = <not relevant>
            grades = <not relevant>
            table.add_column(f"[text] {subject.get_text()}", justify="center", style="info")

            for grade in grades:
                table.add_row(f"{grade.get_text()}")

    return table

Where "subject" is <class 'bs4.element.Tag'> (subject.get_text() returns a string containing what I want to be columns "a", "b"... etc.)
And "grades" is <class 'bs4.element.ResultSet'> (behaves basically the same way a list does.)

With this code, the columns render fine and all relevant data gets to the "a" column fine, but not on "b".

a | b
1 | 
2 | 
3 |
4 | 

If I change add_column and add_row into console.prints I get a, 1-4 from a, then b, 1-4 from b... etc
Like this:

a
1
2
3
4

b
1
2
3
4

What could I change to reach my desired output?

a | b
1 | 1
2 | 2
3 | 3
4 | 4

Note that the values (from a, b... etc) are not the same, I'm using these numbers to illustrate the order in which I get the actual data
