【openpyxl】总结最近使用到的openpyxl方法

单元格嵌入图片

from openpyxl.drawing.image import Image
from openpyxl.drawing.spreadsheet_drawing import AnchorMarker, TwoCellAnchor
from openpyxl.workbook import Workbook

wb = Workbook()
sheet = wb.create_sheet('Sheet1')


def cell_insert_image(sub_sheet, img_path, row_index, col_index):
    # 读取图像
    img = Image(img_path)
    # 左上角固定一个单元格,索引从0开始，AnchorMarker(列,微调,行,微调)
    _from = AnchorMarker(row_index, 50000, col_index, 50000)
    # 右下角固定到另一个单元格
    to = AnchorMarker(row_index + 1, -50000, col_index + 1, -50000)
    img.anchor = TwoCellAnchor('twoCell', _from, to)
    sub_sheet.add_image(img)
    # 设置的行高和列宽
    sub_sheet.row_dimensions[2].height = 100
    sub_sheet.column_dimensions['B'].width = 100


cell_insert_image(sheet, r"d69160564a32f8e1ba6b36ae5831f069.jpg", 1, 1)
wb.save("单元格嵌入图片.xlsx")

调节行高和列宽

sub_sheet.row_dimensions[2].height = 100 #索引从1开始
sub_sheet.column_dimensions['B'].width = 100

合并单元格

import openpyxl

wb = openpyxl.load_workbook('单元格嵌入图片.xlsx')
sheet = wb['Sheet']

# 合并第一行的第1-3列的单元格
sheet.merge_cells(start_row=1, end_row=1, start_column=1, end_column=3)
# 合并第一列的第3-4行
sheet.merge_cells(start_row=3, end_row=4, start_column=1, end_column=1)

wb.save('单元格嵌入图片.xlsx')

自动换行

import openpyxl
from openpyxl.styles import Alignment

wb = openpyxl.load_workbook('单元格嵌入图片.xlsx')
sheet = wb['Sheet2']
for cell in sheet['B']:
    cell.alignment = Alignment(wrapText=True)
wb.save('单元格嵌入图片.xlsx')

按列插入数据

import openpyxl
from openpyxl.cell.cell import ILLEGAL_CHARACTERS_RE
from openpyxl.utils import column_index_from_string


def insert_list_data_to_column(sub_sheet, list_data, column_name, start_row=1):
    col_index = column_index_from_string(column_name)
    for row_index in range(start_row, start_row + len(list_data)):
        col_val = list_data[row_index - start_row]
        try:
            sub_sheet.cell(row=row_index, column=col_index, value=col_val)
        except Exception as e:
            col_val = ILLEGAL_CHARACTERS_RE.sub(r'', col_val)
            sub_sheet.cell(row=row_index, column=col_index, value=col_val)


insert_data = {'A': ['测试数据', 1, 2, 3, 4, 5,6],
               'B': ['测试结果', 'passed', 'failed', 'passed', 'passed', 'passed', 'passed']}
wb = openpyxl.load_workbook('单元格嵌入图片.xlsx')
sheet = wb.create_sheet("Sheet3")
for column_name, list_value in insert_data.items():
    insert_list_data_to_column(sheet, list_value, column_name=column_name, start_row=1)
wb.save('单元格嵌入图片.xlsx')

tableWidget数据导出到excel

注意:openpyxl的行列索引都是从1开始，单元格的数据类型是str

import openpyxl
from PyQt5.QtWidgets import QTableWidget

wb = openpyxl.Workbook()
ws = wb.active
# tableWidget不再赘述其定义方式
# 插入表头
tableWidget: QTableWidget
for index in range(tableWidget.colorCount()):
    ws.cell(row=1, column=index + 1, value=tableWidget.horizontalHeaderItem(index).text())
# 插入数据
for row in range(tableWidget.rowCount()):
    for col in range(tableWidget.colorCount()):
        item = tableWidget.item(row, col)
        if item is not None:
            ws.cell(row=row + 2, column=col + 1, value=str(item.text()))
wb.save("导出.xlsx")
