# Intuition\nwe use concat method to solve this problem\n# Approach\nwe use concat method of pandas which takes array of data frames and axis to join them\n# Complexity\n- Time complexity:\nO(n)\n- Space complexity:\nO(1)\n# Code\n```\nimport pandas as pd\n\ndef concatenateTables(df1: pd.DataFrame, df2: pd.DataFrame) -> pd.DataFrame:\n    // return result of using pandas concat method to join dataframes\n    return pd.concat([df1, df2], axis=0)\n```
