设置表头单元格的颜色

fill = PatternFill("solid", fgColor='FF000000')
font = Font(color='00FFFFFF')
for index, v in enumerate(header):
  d = self.ws.cell(row=1, column=index + 1)
  d.value = v
  d.fill = fill
  d.font = font

设置表头单元格的长度

self.ws.column_dimensions[row[0]].width = row[1]

单元格保存图片

# 获取图片
img = Image(image_path)
# 设置图片宽高
img.width, img.height = 100, 100
# 保存图片
self.ws.add_image(img, f'F{index_row + 2}')
# 设置图片单元格高度；宽度由header设置
self.ws.row_dimensions[index_row + 2].height = 100
