原excel有合併單元格這種格式，openpyxl打開然後保存邊框消失的問題

python3.5 openpyxl2.5可以用這個文件解決

文件名爲：fix_border.py，代碼見下面的代碼片

在你寫代碼的那個文件裏導入該文件
from fix_border import patch_worksheet
然後在load文件前加上patch_worksheet()
全部代碼爲

    ws = opx.load_workbook(filename1)
    # fix_border.patch_worksheet()
    ws.save(filename2)

fix_border.py代碼爲

openpyxl 刪除行操作，合併單元格格式混亂的問題

openpyxl在採取刪除行操作後，即sheet.delete_rows(row,1)，即便使用了上面的patch_worksheet，但是還是不能解決這個單元格格式混亂的情況，目前沒有找到解決的方案。
