asp.net core angular和ng2智能表从数据库获取数据

朋友们。我刚开始学习asp.net核心和angular。我使用角度6。我想使用ng2智能表从mssql数据库输出一个表。如何编写数据和CRUD操作的输出函数。请帮帮我

我的代码

它是我的控制器

using System.Collections.Generic;
using System.Linq;
using Microsoft.AspNetCore.Mvc;
using WebApplication12.Models;

namespace WebApplication12.Controllers
{
    [Route("api/otchets")]
    public class OtchetController : Controller
    {
        web_celContext db;

        public OtchetController(web_celContext context)
        {
            db = context;

        }
        [HttpGet]
        public IEnumerable<Otchet> Get()
        {
            return db.Otchet.ToList();
        }

        [HttpGet("{id}")]
        public Otchet Get(int id)
        {
            Otchet otchet = db.Otchet.FirstOrDefault(x => x.Id == id);
            return otchet;
        }




        [HttpPost]
        public IActionResult Post([FromBody]Otchet otchet)
        {
            if (ModelState.IsValid)
            {
                db.Otchet.Add(otchet);
                db.SaveChanges();
                return Ok(otchet);
            }
            return BadRequest(ModelState);
        }

        [HttpPut("{id}")]
        public IActionResult Put(int id, [FromBody]Otchet otchet)
        {
            if (ModelState.IsValid)
            {
                db.Update(otchet);
                db.SaveChanges();
                return Ok(otchet);
            }
            return BadRequest(ModelState);
        }

        [HttpDelete("{id}")]
        public IActionResult Delete(int id)
        {
            Otchet otchet = db.Otchet.FirstOrDefault(x => x.Id == id);
            if (otchet != null)
            {
                db.Otchet.Remove(otchet);
                db.SaveChanges();
            }
            return Ok(otchet);
        }
    }
}

这是home1.ts

它是home1.component.html

<ng2-smart-table [settings]="settings" [source]="otchets"></ng2-smart-table>
