python xlwt，xlutils 在excel里面如何插入一行数据

就是把插入行之后值重新输出来。

import xlwt;

import xlrd;

from xlutils.copy import copy;

#styleBoldRed = xlwt.easyxf('font: color-index red, bold on');

#headerStyle = styleBoldRed;

#wb = xlwt.Workbook();

#ws = wb.add_sheet('sheetName');

#ws.write(0, 0, "Col1", headerStyle);

#ws.write(0, 1, "Col2", headerStyle);

#ws.write(0, 2, "Col3", headerStyle);

#wb.save('fileName.xls');

#open existed xls file

oldWb = xlrd.open_workbook("fileName.xls", formatting_info=True);

oldWbS = oldWb.sheet_by_index(0)

newWb = copy(oldWb);

newWs = newWb.get_sheet(0);

inserRowNo = 1

newWs.write(inserRowNo, 0, "value1");

newWs.write(inserRowNo, 1, "value2");

newWs.write(inserRowNo, 2, "value3");

for rowIndex in range(inserRowNo, oldWbS.nrows):

for colIndex in range(oldWbS.ncols):

newWs.write(rowIndex + 1, colIndex, oldWbS.cell(rowIndex, colIndex).value);

newWb.save('fileName.xls');

print "save with same name ok";
