You can do this in different ways. The method usually used is to loop in the data array and add rows in a table in which width of each column is set. Please see the sample in jQuery
你可以用不同的方式来做到这一点。通常使用的方法是在数据数组中循环并在设置了每列宽度的表中添加行。请参阅 jQuery 中的示例
var data = [
{
no: 1,
name: "ITEM1",
price1: "9.00",
perc: "0%",
price2: "9.00"},
{
no: 2,
name: "ITEM-GET01",
price1: "9.00",
perc: "12%",
price2: "5.00"}
];
//$("#list tr").remove();
$(data).each(function(index, item) {
$("#list").append('<tr><td width="50">' + item.no + '</td><td width="100">' + item.name + '</td><td width="100">' + item.price1 + '</td>' + item.perc + '<td width="100">' + item.price2 + '</td></tr>');
})
