 //win.setBackgroundColor = 'white';
  var table = Ti.UI.createTableView();
  var tableData = [];
  var json, fighters, fighter, i, row, nameLabel, nickLabel,offerType,offerName;

 var xhr = Ti.Network.createHTTPClient({
  onload: function() {
// Ti.API.debug(this.responseText);

json = JSON.parse(this.responseText);
for (i = 0; i < json.length; i++) {

    console.log("json = %d",i);
    offerType = json[i].offerType;
    row = Ti.UI.createTableViewRow({
        height:'60dp'
    });
    nameLabel = Ti.UI.createLabel({
        text:offerType,
        font:{
            fontSize:'24dp',
        fontWeight:'bold'
    },
    height:'auto',
    left:'10dp',
    top:'5dp',
    color:'#000',
    touchEnabled:false
    });
    offerName = json[i].offerName;
    nickLabel = Ti.UI.createLabel({
    text:'"' + fighter.nickname + '"',
    font:{
        fontSize:'16dp'
    },
    height:'auto',
    left:'15dp',
    bottom:'5dp',
    color:'#000',
    touchEnabled:false
    });

    row.add(nameLabel);
    row.add(nickLabel);
    tableData.push(row);
    }

table.setData(tableData);
},
 onerror: function(e) {
Ti.API.debug("STATUS: " + this.status);
Ti.API.debug("TEXT:   " + this.responseText);
Ti.API.debug("ERROR:  " + e.error);
alert('There was an error retrieving the remote data. Try again.');
},
timeout:5000
});

xhr.open("GET", url);
xhr.send();

我怎样才能实现我的目标，在此先感谢。

您的代码非常接近。我确实做了一些更改，因此您必须比较它们以了解如何修复它。此示例读取您的服务并在表格中显示 2 个条目。

请参阅代码中的注释，详细说明它是如何更改的。
