我通过pandas.read_html
Column1 Column2 Column3 Column4 Column5
0 Entry_1 Value_1 Record_1 test_1 NaN
1 Entry_2 Value_2 Record_2 test_2 NaN
2 Entry_3 Value_3 Record_3 test_3 NaN
3 Entry_4 Value_4 Record_4 test_4 NaN
4 Entry_5 Value_5 Record_5 test_5 NaN
5 Entry_6 Value_6 Record_6 test_6 NaN
6 Entry_7 Value_7 - Record_7 test_7
如何使用pandas将Column4和Column5移回1个空格，以便它自行对齐？
