使用工作表格式将％符号添加到列

Question

我想在列中的值上添加“％”符号（我实际上不想将其转换为百分比，只想添加符号）。我尝试了下面的代码，将值转换为百分比，然后在值后添加（％）符号。有什么办法可以添加标志。

Answer 1

  

有什么方法可以添加符号。

不完全是。您还需要通过将该数字除以100来将其转换为百分比。然后它应该可以正常工作。这是默认的Excel行为，而不仅仅是XlsxWriter的。

这里是一个例子：

import xlsxwriter

workbook = xlsxwriter.Workbook('percent.xlsx')
worksheet = workbook.add_worksheet()

format2 = workbook.add_format({'num_format': '0.0%'})
worksheet.set_column('D:D', 40, format2)

worksheet.write(0, 3, .1)
worksheet.write(1, 3, .25)
worksheet.write(2, 3, .5)
worksheet.write(3, 3, .75)

workbook.close()

这是输出：

Answer 2

在这种情况下，我认为您可以这样做：

Sub test()
Dim myRange As Range

Set myRange = Sheets("Sheet1").Range("D1:D100")

For Each c In myRange
    Sheets("Sheet1").Cells(c.Row, c.Column) = Sheets("Sheet1").Cells(c.Row, c.Column) & "%"
Next c
End Sub
