各位大佬，求救啊

需求：ajax局部刷新表格数据
所用：python flask+jq ajax+分页
问题：前台成功接收到后台传的json数据，但不知道怎么实现“替换表格原有的数据，而且保持原来分页的状态（20条/页）”
teacher.html：

$(function b() {
$.ajax({
url: "http://127.0.0.1:5000/teacher_info/delete_many/",
type: "POST",
data: k,
dataType:"json",
success: function (resp) {
if (resp) {
...    // 这里就不知道怎么写了（原本想拼接出新表格str， 再用$("#table").html(str);替换原表格，但发现由于还有分页功能，替换后所有记录都只在第一页，而且表格样式有所改变

demo.py：

# 删除
@app.route('/teacher_info/delete_many/',methods=['GET','POST'])
def delete_many_teacher():
    result = request.form.get('data', '')
    for i in json.loads(result):
        id = int(i)
        teacher = Teacher_info.query.filter(Teacher_info.id == id).first()
        db.session.delete(teacher)
        db.session.commit()
    item = []
    teachers = Teacher_info.query.all()
    for teacher in teachers:
        obj = teacher.to_json()    # 调用了该类的自定义方法（将实例对象转化为json）
        item.append(obj)
    return json.dumps(item)    # item是 [ {},{},...{} ]。如[{'id':1,'name': '张三',  'age':18}, {'id':2,'name': '李四', 'age': 21,...]

# 分页：
@app.route('/teacher_info/',methods=['GET','POST'])
def teacher_info(page=None):
    paginate = Teacher_info.query.order_by(Teacher_info.id).paginate(page=page, per_page=20, error_out=False)
    teachers = paginate.items
    return render_template('teacher_info.html', paginate=paginate, teachers=teachers)

teacher.html：

{% for teacher in teachers %}
<tr >
<td  height="20" bgcolor="#FFFFFF"><div align="center"><input type="checkbox" name="checkbox2" value="checkbox"/></div></td>    // 选择方框
<td height="20" bgcolor="#FFFFFF"><div align="center" class="STYLE1"><div id="id" align="center">{{ teacher.id }}</div></div></td>  // id列
<td height="20" bgcolor="#FFFFFF"><div id="username" align="center"><span class="STYLE1">{{ teacher.name }}</span></div></td>  // name列
<td height="20" bgcolor="#FFFFFF"><div id="username" align="center"><span class="STYLE1">{{ teacher.age}}</span></div></td>  // age列
</tr>
{% endfor %}
