# Intuition
<!-- Describe your first thoughts on how to solve this problem. -->
Combine the two dataframes vertically by combining along rows

# Approach
<!-- Describe your approach to solving the problem. -->
Use the .concat() method

# Complexity
- Time complexity:
<!-- Add your time complexity here, e.g. $$O(n)$$ -->
O(n + m) for the size of the dataframes being concatenated 

- Space complexity:
<!-- Add your space complexity here, e.g. $$O(n)$$ -->
O(n + m) for the size of the dataframes being concatenated

# Code
```pythondata []
import pandas as pd

def concatenateTables(df1: pd.DataFrame, df2: pd.DataFrame) -> pd.DataFrame:
    
    result = pd.concat([df1, df2])

    return result
```
