javascript实现表格排序 编辑 拖拽 缩放

时间：2021-05-26

简单表格排序

可以双击编辑 自定义编辑后的 规则

可拖动列进行列替换

可推动边框进行列宽度的缩放

复制代码 代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://pare :function(n,type){
return function (a1,a2){
var convert ={
int : function(v){return parseInt(v)},
float : function(v){return parseFloat(v)},
date : function(v){return v.toString()},
string : function(v){return v.toString()}
};
!convert[type]&&(convert[type]=function(v){return v.toString()});
a1 =convert[type](a1.cells[n].innerHTML);
a2 =convert[type](a2.cells[n].innerHTML);
return a1==a2?0:a1<a2?-1:1;
};
},

已知BUG：

ie6下 中文不自动换行

非ie下字母和数字也不自动换行确实让人恼火

chrome浏览器下点击运行好像问题很大 拿到本地测试会比较好
