解析：
遍历取出表，顺序是行从上往下，列从左往右，将数据存进数组，下面再拼接成表。

如何用jquery把文件导出成csv格式文件
兼容性好点就发送内容到服务器，又服务器处理，设置"Content-Disposition"响应头"attachment;filename="xxx.csv"")
要不就只能IE浏览器下的document.execCommand('SaveAs', 'xxx.csv');了，兼容性不是很好，而且好像指定的文件名和后缀没效果。。

Java后台代码读取html页面table中的内容并保存到当地为.csv文件
table内容是从数据库取的吧，你也可以从数据库读取啊。再写入cvs就行了，没必要去解析这个table
Python 和 BeautifulSoup 怎么把 html table 处理成 csv
Python 和 BeautifulSoup 把 html table 处理成 csv，代码如下：
#coding:utf8
import urllib
import urllib2
import cookielib
import re
import csv
import codecs
from bs4 import BeautifulSoup
wiki = ''
header = {'User-Agent': 'Mozilla/5.0'}
req = urllib2.Request(wiki,headers=header)
page = urllib2.urlopen(req)
soup = BeautifulSoup(page)
name = "" #名字
creater = "" #归属
first = "" #首次公开发布的时间
latest = "" #最新稳定版本
cost = "" #售价
licence = "" #授权条款
table = soup.find("table", {"class" : "sortable wikitable"})
f = open('table.csv', 'w')
csv_writer = csv.writer(f)
td_th = re.compile('t[dh]')
for row in table.findAll("tr"):
cells = row.findAll(td_th)
if len(cells) == 6:
name = cells[0].find(text=True)
if not name:
continue
creater = cells[1].find(text=True)
first = cells[2].find(text=True)
latest = cells[3].find(text=True)
cost = cells[4].find(text=True)
licence = cells[5].find(text=True)
csv_writer.writerow([ x.encode('utf-8') for x in [name, creater, first, latest, cost, licence]])
f.close()
Javascript实现把网页中table的内容导出到excel中的几种方法
一、 直接拷贝整个表格到EXCEL中二、 通过遍历表格，给EXCEL中相应的单元格赋值。三、 把表格中的内容提取出来，利用IE的另存为.csv的格式。各方法的好处：1. 直接拷贝表格，能够保留表格中的原有的格式，比如，列，行的合并，对齐方式，底色等等，2. 通过遍历表格，比较灵活，可以遍历表格某些需要部分的内容。3. 利用IE的另存为，不用创建ActiveXObject对象，可以处理表格合并方面的问题。各方法的缺点：1. 可能弹出脚本错误：Automation不能创建对象。解决方法：启用IE安全设置中的：对没有标记为安全的ActiveX控件进行初始化和脚本运行。由于整个表格复制到EXCEL中，给表格加个标题，并加入到EXCEL中可能会遇到麻烦。解决方法：首先在表格中加入第一行trtd colspan="x" align="center"/td/trX，表示整个表格的列数，复制完整个表格后,加如下代码，oSheet为当前活动的sheet.oSheet.Range(oSheet.Cells(1, 1), oSheet.Cells(1, x)).value = "表格标题";//设置标题oSheet.Rows(1).Font.Size = 16; //设置文字大小oSheet.Rows(1).Font.Name = "宋体";//设置文字字体注：以下属性我没用着，可能有用，也可能会报错oSheet.Range(oSheet.Cells(1,1), oSheet.Cells(1,14)).mergecells=true; //合并单元格oSheet.Range(oSheet.Cells(1,1), oSheet.Cells(1,14)).Interior.ColorIndex=6;//设置底色?oSheet.Range(oSheet.Cells(1,1), oSheet.Cells(1,14)).Font.ColorIndex=5;//设置字体色?oSheet.Rows(1).RowHeight=20; //设置列高oSheet.Cells(iRow,iCol).Halignment=’2’//设置字体居中2. 可能弹出脚本错误：Automation不能创建对象（解决方法如上）。表格内容写入到EXCEL中无表格线（未解决）且有单元格合并时会有问题，解决方法：合并单元格后再写数据。oSheet.Range(oSheet.Cells(1,1), oSheet.Cells(1,14)).mergecells=true; //合并单元格3. 表格内容写入到EXCEL中无表格线（未解决）表格格式复杂时，会有问题，（rowspan1 or colspan1）,解决方法：一般都是表头格式比较复杂，可先把表头写死，然后再循环写其他数据。代码如下：!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"HTMLHEADTITLE New Document /TITLE
