Question

我有一个JSON对象，我从Ajax请求返回，格式如下：

InputStream is;
TextView tv;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.my_layout);

    tv = (TextView)findViewById(R.id.tv);

    try {
        is = getAssets().open("html.txt");
        tv.setText(Html.fromHtml(convertStreamToString(is)));
    } catch (Exception e) {
        e.printStackTrace();
    }

}

public static String convertStreamToString(InputStream is) throws Exception {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();
    String line = null;
    while ((line = reader.readLine()) != null) {
        sb.append(line).append("\n");
    }
    reader.close();
    return sb.toString();
}

如何生成一个数据表对象，其列名为＆＃34; Sales1＆＃34;，＆＃34; Sales2＆＃34;等，以及每个相应列下方各行中的值？另外，假设我想在值的左侧和右侧有行标签，那可能吗？

这就是如何生成一个数据表对象，其列名为＆＃34; Sales1＆＃34;，＆＃34; Sales2＆＃34;等。

＆＃13;

$(document).ready(function() {
  var source =
  
  {data:
  [{"Sales1": "100", "Sales2": "200", "Sales3": "400"},
   {"Sales1": "150", "Sales2": "250", "Sales3": "450"}]};
   
  $('#myDataTable').dataTable({
    "data": source.data,
    "aoColumns": [{
      "mData": 'Sales1',
    }, {
      "mData": 'Sales2'
    }, {
      "mData": 'Sales3'
    }]
  })
})

      <th>Sales2</th>
      <th>Sales3</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>
