我刚刚实现了一个包装类，它跟踪输入项的宽度。看起来效果不错。import arial10

class FitSheetWrapper(object):

"""Try to fit columns to max size of any entry.

To use, wrap this around a worksheet returned from the

workbook's add_sheet method, like follows:

sheet = FitSheetWrapper(book.add_sheet(sheet_name))

The worksheet interface remains the same: this is a drop-in wrapper

for auto-sizing columns.

"""

def __init__(self, sheet):

self.sheet = sheet

self.widths = dict()

def write(self, r, c, label='', *args, **kwargs):

self.sheet.write(r, c, label, *args, **kwargs)

width = arial10.fitwidth(label)

if width > self.widths.get(c, 0):

self.widths[c] = width

self.sheet.col(c).width = width

def __getattr__(self, attr):

return getattr(self.sheet, attr)

所有的魔法都在John Yeung's ^{} module里。这对于默认的Excel字体Arial 10有很好的宽度。如果要使用其他字体编写工作表，则需要更改fitwidth函数，最好考虑传递给FitSheetWrapper.write的style参数。
