Python教程：熟练使用openpyxl为指定区域设置边框为粗框线

<p><span>import openpyxl
from openpyxl.styles import Side, Border, colors

#定义边框样式
def my_border(t_border, b_border, l_border, r_border):
    border = Border(top=Side(border_style=t_border, color=colors.BLACK),
                    bottom=Side(border_style=b_border, color=colors.BLACK),
                    left=Side(border_style=l_border, color=colors.BLACK),
                    right=Side(border_style=r_border, color=colors.BLACK))
    return border

#初始化制定区域边框为所有框线
def format_border(s_column, s_index, e_column , e_index):
    for row in tuple(sheet[s_column + str(s_index):e_column + str(e_index)]):
        for cell in row:
            cell.border = my_border('thin', 'thin', 'thin', 'thin')

#给指定区域设置粗匣框线
def set_solid_border(area_list):
    for area in area_list:
        s_column = area[0]
        s_index = area[1]
        e_column = area[2]
        e_index = area[3]
        #设置左粗框线
        for cell in sheet[s_column][s_index - 1:e_index]:
            cell.border = my_border(cell.border.top.style, cell.border.bottom.style,
                                    'medium', cell.border.right.style)
        # 设置右粗框线
        for cell in sheet[e_column][s_index - 1:e_index]:
            cell.border = my_border(cell.border.top.style, cell.border.bottom.style,
                                    cell.border.left.style, 'medium')
        # 设置上粗框线
        for row in tuple(sheet[s_column + str(s_index):e_column + str(s_index)]):
            for cell in row:
                cell.border = my_border('medium', cell.border.bottom.style,
                                        cell.border.left.style, cell.border.right.style)
        # 设置下粗框线
        for row in tuple(sheet[s_column + str(e_index):e_column + str(e_index)]):
            for cell in row:
                cell.border = my_border(cell.border.top.style, 'medium',
                                        cell.border.left.style, cell.border.right.style)
