**Task Overview:**

Print the two-dimensional list `mult_table` by row and column. On each line, each character is separated by a space. Hint: Use nested loops.

**Sample Output with Input `'1 2 3,2 4 6,3 6 9'`:**

```
1 | 2 | 3
2 | 4 | 6
3 | 6 | 9
```

**Code Explanation:**

```python
1  user_input = input()
2  lines = user_input.split(',')
3  
4  # This line uses a construct called a list comprehension, introduced elsewhere,
5  # to convert the input string into a two-dimensional list.
6  # Ex: '1 2, 2 4' is converted to [ [1, 2], [2, 4] ]
7  
8  mult_table = [[int(num) for num in line.split()] for line in lines]
```

- **Line 1:** Retrieves user input.
- **Line 2:** Splits the input string by commas, creating a list of strings (each representing a row).
- **Line 8:** Converts each row string into a list of integers using list comprehension, producing a two-dimensional list `mult_table`.
