🧑‍💻 Usage

Convert lists to ASCII tables

from table2ascii import table2ascii

output = table2ascii(
    header=["#", "G", "H", "R", "S"],
    body=[["1", "30", "40", "35", "30"], ["2", "30", "40", "35", "30"]],
    footer=["SUM", "130", "140", "135", "130"],
)

print(output)

"""
╔═════════════════════════════╗
║  #     G     H     R     S  ║
╟─────────────────────────────╢
║  1    30    40    35    30  ║

╟─────────────────────────────╢
║ SUM   130   140   135   130 ║
╚═════════════════════════════╝
"""

Set first or last column headings

from table2ascii import table2ascii

output = table2ascii(
    body=[["Assignment", "30", "40", "35", "30"], ["Bonus", "10", "20", "5", "10"]],
    first_col_heading=True,
)

print(output)

"""

║    Bonus   ║ 10   20    5   10 ║
╚════════════╩═══════════════════╝
"""

Set column widths and alignments

from table2ascii import table2ascii, Alignment

output = table2ascii(
    header=["#", "G", "H", "R", "S"],
    body=[["1", "30", "40", "35", "30"], ["2", "30", "40", "35", "30"]],
    first_col_heading=True,
    column_widths=[5] * 5,  # [5, 5, 5, 5, 5]
    alignments=[Alignment.LEFT] + [Alignment.RIGHT] * 4, # First is left, remaining 4 are right
)

print(output)

"""

Use a preset style

from table2ascii import table2ascii, PresetStyle

output = table2ascii(
    header=["First", "Second", "Third", "Fourth"],
    body=[["10", "30", "40", "35"], ["20", "10", "20", "5"]],
    column_widths=[10] * 4,
    style=PresetStyle.ascii_box
)

print(output)

"""

Define a custom style

Check TableStyle for more info and PresetStyle for examples.

from table2ascii import table2ascii, TableStyle

my_style = TableStyle.from_string("*-..*||:+-+:+     *''*")

output = table2ascii(
    header=["First", "Second", "Third"],
    body=[["10", "30", "40"], ["20", "10", "20"], ["30", "20", "30"]],
    style=my_style

print(output)

"""
