我刚刚实现了一个包装器类，该类可以在您输入物品时跟踪它们的宽度。看来效果很好。
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)
所有的魔力都在杨John的arial10模块中。对于默认的Excel字体Arial 10，它具有良好的宽度。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style传递给的参数FitSheetWrapper.write。
