Openpyxl自动高度

Question

我正在设置换行文字。但当我使用换行时，不会自动更改高度。如何设置自动高度行？

Answer 1

如果您的数据存储在DataFrame中，我建议您使用StyleFrame。 它可以自动调整列的宽度和行的高度，还具有一些不错的功能。

styleframe

Answer 2

尝试：

col_width = []
for i in range(len(next(ws.iter_rows()))):
    col_letter = get_column_letter(i + 1)

    minimum_width = 20
    current_width = ws.column_dimensions[col_letter].width
    if not current_width or current_width < minimum_width:
        ws.column_dimensions[col_letter].width = minimum_width

    col_width.append(ws.column_dimensions[col_letter].width)

for i, row in enumerate(ws):
    default_height = 12.5  # Corresponding to font size 12

    multiples_of_font_size = [default_height]
    for j, cell in enumerate(row):
        wrap_text = True
        vertical = "top"
        if cell.value is not None:
            mul = 0
            for v in str(cell.value).split('\n'):
                mul += math.ceil(len(v) / col_width[j]) * cell.font.size

            if mul > 0:
                multiples_of_font_size.append(mul)

        cell.alignment = Alignment(wrap_text=wrap_text, vertical=vertical)

    original_height = ws.row_dimensions[i + 1].height
    if original_height is None:
        original_height = default_height

    new_height = max(multiples_of_font_size)
    if original_height < new_height:
        ws.row_dimensions[i + 1].height = new_height

但这并不完美。如果您想要更好的字体，您可能必须使用单空间字体或pillow。

您需要查看相关行的RowDimension对象，特别是height属性：

rd = ws.row_dimensions[3] # get dimension for row 3
rd.height = 25 # value in points, there is no "auto"
