如何利用Python批量处理行、列和单元格详解

for i in workbook.sheets:
	value = i.range('A1').expand('table')
	value.column_width = 12
	value.row_height = 20
workbook.save()

#遍历工作表
for j in workbook.sheets:
	# 获取最后一行
	row_num = j['A1'].current_region.last_cell.row
	# 数据格式修改
	j['A2:A{}'.format(row_num)].number_format = 'm/d'
	j['D2:D{}'.format(row_num)].number_format = '￥#,##0.00'
workbook.save()
workbook.close()

j['A1:H1'].api.Font.Name = '宋体'

j['A1:H1'].api.Font.Size= 10  # 10磅

j['A1:H1'].api.Font.Bold= True  

# 白色
j['A1:H1'].api.Font.Color= xw.utils.rgb_to_int((255,255,255)) 

# 填充颜色为黑色
j['A1:H1'].Color= xw.utils.rgb_to_int((0,0,0)) 

# 水平对齐方式为 居中
j['A1:H1'].api.HorizontalAlignment = xw.constants.HAlign.xlHAlignCenter

# 垂直对齐方式为 居中
j['A1:H1'].api.VerticalAlignment= xw.constants.VAlign.xlVAlignCenter

# 遍历所有的单元格
for cell in j['A1'].expand('table'):
	for b in range(7,12):
		# 设置单元格的边框线型
		cell.api.Borders(b).LineStyle = 1
		# 设置单元格的边框粗细
		cell.api.Borders(b).Weight = 2

# 遍历工作表
for j in eorkbook.sheets:
	# 获取工作表数据
	value = j['A2'].expand('table').value
	#按行遍历工作表数据
	for index,val in enumerate(value):
		# 判断行数据是否是这个
		if val == ['背包',16,65]:
			# 是的话替换为新数据
			value[index] = ['双肩包',36,79]
	#将完成替换的数据写入工作表中
	j['A2'].expand('table').value = value
workbook.save()

enumerate(sequenxe,[start=0])
# start 是索引的起始位置

#按行遍历工作表数据
for index,val in enumerate(value):
	# 修改第三个单元格，即第index行，第 3列，下标是从0开始的
	val[2] = val[2] + 1
	# 替换整行数据
	value[index] = val
