更改Excel工作表中现有选项卡的列宽

Question

我将数据框（df）作为新标签（“打印”）添加到现有的excel文件中。我在调整列宽时遇到困难吗？

代码

book = load_workbook('file.xlsx')
writer = pd.ExcelWriter('file.xlsx', engine = 'openpyxl')
writer.book = book
df.to_excel(writer,sheet_name = 'Print')
worksheet = writer.sheets['Print']
worksheet.set_column('B:B', 40) #This does not work

Answer 1

writer = pd.ExcelWriter('file.xlsx', engine='openpyxl')
writer.book = book
df.to_excel(writer, sheet_name='Print')
sheet = book.get_sheet_by_name('Print')
sheet.column_dimensions['B'].width = 40
writer.save()

Answer 2

我从没有使用过，也没有做过，但是我只是在Google上搜索“ worksheet.set_column”并发现了这一点： https://xlsxwriter.readthedocs.io/worksheet.html

该函数的语法为

set_column(first_col, last_col, width, cell_format, options)

所以我想说的答案是：

worksheet.set_column(2, 2, 40)
