python删除单元格_Openpyxl删除单元格/清除内容

我正在寻找删除或清除某些单元格内容的方法。在搜索之后,使用openpyxl似乎不是一件简单的事情。找到this similar question,建议将单元格设置为“无”。我这样做了,但是当我尝试附加数据时,它仍然将它附加到我设置为“无”的所有行的末尾。def clear_sheet(this_sheet):

'''

Clear all cells starting from third row. we keep our header and

replaces other rows content by None

'''

dst_wb=openpyxl.load_workbook(dest_filename, read_only=False, keep_vba=True)

dst_ws=dst_wb.get_sheet_by_name(this_sheet)

#We kee the header located in row 2, and set the rest to None

if dst_ws.cell('A3').value is not None: #check if already cleared content

for row in dst_ws.iter_rows(row_offset=2):

for cell in row:

cell.value=None

dst_wb.save(dest_filename)

def copy_data(searchMilestone):

'''

gets data from the sequence file

'''

dst_wb=openpyxl.load_workbook(dest_filename, read_only=False, keep_vba=True)

dst_ws=dst_wb.get_sheet_by_name(sequence_sheet)

data =[]

print dst_ws.max_row #here should return 3, but it seems it is counting all the cells we set to None

for i in xrange(sequenceWs.nrows):

#this reading part is done using xlrd module

milestone=sequenceWs.cell(i,1).value

execution=sequenceWs.cell(i,2).value

system=sequenceWs.cell(i,16).value

if searchMilestone in milestone and 'WC' in execution:

#copy some data

line=[data, data, data]

dst_ws.append(line)

dst_wb.save(dest_filename)

在向其写入数据的工作簿中,我有冻结窗格和一些筛选器(显示所有数据)。对清除内容后如何强制从第3行追加有何建议?我正在使用python 2.7和openpyxl2.3。
