XlsxWriter设置全局字体大小

Question

首次创建工作簿时，如何使用xlswriter永久设置字体大小？

我试过：

book = xlsxwriter.Workbook(os.getcwd() + '\\test.xlsx')
sheet1 = book.add_worksheet()
format = book.add_format()
format.set_font_size(10)

但我仍然在输出中得到默认大小11。怎么了？

Answer 1

1，对于单单元格字体大小，必须将format传递给write，如下所示：

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

# Add a bold format to use to highlight cells.
bold = workbook.add_format({'bold': True})
# Add a font size 10 format.
format = workbook.add_format()
format.set_font_size(10)
# Write some simple text.
worksheet.write('A1', 'Hello', format)

# Text with formatting.
worksheet.write('A2', 'World', bold)

# Write some numbers, with row/column notation.
worksheet.write(2, 0, 123)
worksheet.write(3, 0, 123.456)


workbook.close()

Hello将设置为字体大小10。

更新： 2.对于所有单元格的字体大小，可以设置工作簿的默认格式：

import xlsxwriter
workbook = xlsxwriter.Workbook('demo.xlsx')

# default cell format to size 10 
workbook.formats[0].set_font_size(10)

worksheet = workbook.add_worksheet()


# Write some simple text.
worksheet.write('A1', 'Hello')

worksheet.write('A2', 'World')

# Write some numbers, with row/column notation.
worksheet.write(2, 0, 123)
worksheet.write(3, 0, 123.456)

workbook.close()

所有单元格将更改为字体大小10：
