简单封装类：

from openpyxl import load_workbook
from openpyxl import Workbook
from openpyxl.chart import BarChart, Series, Reference, BarChart3D
from openpyxl.styles import Color, Font, Alignment
from openpyxl.styles.colors import BLUE, RED, GREEN, YELLOW
class Write_excel(object):
  def __init__(self,filename):
    self.filename = filename
    self.wb = load_workbook(self.filename)
    self.ws = self.wb.active
  def write(self, coord, value):
    # eg: coord:A1
    self.ws.cell(coord).value = value
    self.wb.save(self.filename)
  def merge(self, rangstring):
    # eg: rangstring:A1:E1
    self.ws.merge_cells(rangstring)
    self.wb.save(self.filename)
  def cellstyle(self, coord, font, align):
    cell = self.ws.cell(coord)
    cell.font = font
    cell.alignment = align
  def makechart(self, title, pos, width, height, col1, row1, col2, row2, col3, row3, row4):
    ''':param title:图表名
         pos:图表位置
         width:图表宽度
         height:图表高度
    '''
    data = Reference(self.ws, min_col=col1, min_row=row1, max_col=col2, max_row=row2)
    cat = Reference(self.ws, min_col=col3, min_row=row3, max_row=row4)
    chart = BarChart3D()
