tdedit的代码，用的时候只要改下Table名字，在htm里（/body前）调用一下就OK
tdedit.js
//编辑html表格中的字段td
var tdx = -1;
var isedit = false;
var canleft=true,canright=true,candown=true,canup=true;

var thettd = 0;
function restore(){
for(var i = 4;i<obj.cells.length;i++){
obj.cells.style.backgroundColor="";
obj.cells.style.color="";
}
if(tdx>=(obj.cells.length-1)){
tdx = obj.cells.length-1;
canright=false;
candown=false;
}
else if(tdx<=0){
tdx = 0;
canleft=false;
canup=false;
}
else{
//canleft=true;
// canright=true;
candown=true;
canup=true;
}
}
/*function right(){
tdx++;
restore();
obj.cells[tdx].style.backgroundColor="gray";
obj.cells[tdx].style.color="#FFFFFF";
}
function left(){
tdx--;
restore();
