Раніше у мене була та сама проблема. Я не міг знайти нічого, що могло б мені допомогти, тому в підсумку я створив клас - PrintTable
код нижче. Також є вихід. Використання просто:
ptobj = PrintTable(yourdata, column_captions, column_widths, text_aligns)
ptobj.print()
або в один рядок:
PrintTable(yourdata, column_captions, column_widths, text_aligns).print()
Вихід:
-------------------------------------------------------------------------------------------------------------
Name | Column 1 | Column 2 | Column 3 | Column 4 | Column 5
-------------------------------------------------------------------------------------------------------------
Very long name 0 | 0 | 0 | 0 | 0 | 0
Very long name 1 | 1 | 2 | 3 | 4 | 5
Very long name 2 | 2 | 4 | 6 | 8 | 10
Very long name 3 | 3 | 6 | 9 | 12 | 15
Very long name 4 | 4 | 8 | 12 | 16 | 20
Very long name 5 | 5 | 10 | 15 | 20 | 25
Very long name 6 | 6 | 12 | 18 | 24 | 30
Very long name 7 | 7 | 14 | 21 | 28 | 35
Very long name 8 | 8 | 16 | 24 | 32 | 40
Very long name 9 | 9 | 18 | 27 | 36 | 45
Very long name 10 | 10 | 20 | 30 | 40 | 50
Very long name 11 | 11 | 22 | 33 | 44 | 55
Very long name 12 | 12 | 24 | 36 | 48 | 60
Very long name 13 | 13 | 26 | 39 | 52 | 65
Very long name 14 | 14 | 28 | 42 | 56 | 70
Very long name 15 | 15 | 30 | 45 | 60 | 75
Very long name 16 | 16 | 32 | 48 | 64 | 80
Very long name 17 | 17 | 34 | 51 | 68 | 85
Very long name 18 | 18 | 36 | 54 | 72 | 90
Very long name 19 | 19 | 38 | 57 | 76 | 95
