                       id="payment" class="form-control input-height" 
                       placeholder="Payment" type="text">
            </td>
            <td>{{item.Balance}}</td>

    </tbody>

答案

将ng-if指令与$last项目范围的ng-repeat属性一起使用：

    <tr ng-repeat="item in VisaPaymentList">
        <td>{{item.ShirkaName}}</td>
        <td>{{item.approvals}}</td>
        <td>{{item.CompanyRate}}</td>
        <td>{{item.DateField}}</td>
        <td>    
            <̶i̶n̶p̶u̶t̶ ̶n̶g̶-̶c̶h̶a̶n̶g̶e̶=̶"̶B̶a̶l̶a̶n̶c̶e̶M̶i̶n̶u̶s̶(̶)̶"̶
            <input ng-if="$last" ng-change="BalanceMinus()"
                   ng-model="item.PaymentReceived" autocomplete="off" 
                   ̶i̶d̶=̶"̶p̶a̶y̶m̶e̶n̶t̶"̶ ̶c̶l̶a̶s̶s̶=̶"̶f̶o̶r̶m̶-̶c̶o̶n̶t̶r̶o̶l̶ ̶i̶n̶p̶u̶t̶-̶h̶e̶i̶g̶h̶t̶"̶ ̶
                   name="payment" class="form-control input-height" 
                   placeholder="Payment" type="text">
        </td>
        <td>{{item.Balance}}</td>
    </tr>

当$last是true时，将添加<input>元素。否则<td>元素将为空。
