给价格这一列写id属性(),给显示/隐藏价格写onclick="showorhide(1);"方法。
function showorhide (num){
var a=document.getElementById(""); //写上你价格那列每个单元格的id
var b=document.getElementById("");
var c=document.getElementById("");
var d=document.getElementById("");
if(num==1){
a.style.display="none";
b.style.display="none";
c.style.display="none";
d.style.display="none";
}else{
a.style.display="block";
b.style.display="block";
c.style.display="block";
d.style.display="block";
}
}
function showorhide (num){
var a=document.getElementById(""); //写上你价格那列每个单元格的id
var b=document.getElementById("");
var c=document.getElementById("");
var d=document.getElementById("");
if(num==1){
a.style.display="none";
b.style.display="none";
c.style.display="none";
d.style.display="none";
}else{
a.style.display="block";
b.style.display="block";
c.style.display="block";

}
