如何使用 openpyxl 在 XLSX 文件中逐个单元格地插入和格式化值

Question

I am trying to write an XLSX file using the openpyxl module. I am using the append() method to insert the values row by row. But I want to insert the values cell by cell instead. I would also like to format the cell (font, colour, alignment etc). Please help me.

You can set all that cell by cell (if that is what you need) using openpyxl. Here is a small example which sets the value, name (named_range) and some style of cells in a workbook:

from openpyxl.workbook import Workbook
wb = Workbook()
dest_filename = r'empty_book.xlsx'
ws = wb.worksheets[0]    

name = 'name'

for col_idx in xrange(1, 101):
    col = get_column_letter(col_idx)
    for row in xrange(1, 1001):
        ws.cell('%s%s'%(col, row)).value = '%s%s' % (col, row)
        ws.cell('%s%s'%(col, row)).style.fill.fill_type = 'solid'
        ws.cell('%s%s'%(col, row)).style.fill.start_color.index = openpyxl.style.Color.DARKYELLOW
        wb.create_named_range(name+str(i), ws, '%s%s'%(col, row))

wb.save(filename = dest_filename)

Look up the Style class in the openpyxl documentation to learn more about how to set individual formattings.
