2877. Create a DataFrame from List

Write a solution to create a DataFrame from a 2D list called student_data. This 2D list contains the IDs and ages of some students.

The DataFrame should have two columns, student_id and age, and be in the same order as the original 2D list.

The result format is in the following example.

Example 1:

Input:
student_data:
[
  [1, 15],
  [2, 11],
  [3, 11],
  [4, 20]
]
Output:
+------------+-----+
| student_id | age |
+------------+-----+
| 1          | 15  |
| 2          | 11  |
| 3          | 11  |
| 4          | 20  |
+------------+-----+
