- 前端VUE界面

用到了 element组件 和 avue前台框架 (均需要安装依赖文件)

<template>
<div>
    <avue-crud 
        ref="crud"
        :page="page"

        @search-change="searchChange">

        <template slot="expand" slot-scope="{row}">

- 后台代码

就记录个Controller的代码吧，service那些继承IService这种就得
其它方法 按实时情况修改

@RestController
@RequestMapping("/tenant")
public class TenantController {
    @Autowired
    private TenantService tenantService;
    
    /**
     * 获取租户平台列表
     * @param page
     * @param tenant
     * @return
     */
    @PostMapping("/getTenantList")
    public ResponseEntity<IPage<Tenant>> getTenantList(PageParam<Tenant> page,Tenant tenant) {
        IPage<Tenant> tenantList = tenantService.getTenantList(page,tenant);
        return ResponseEntity.ok(tenantList);
    }

    /**
     * 修改平台租户信息
     * @param tenant
     * @return
     */
    @PostMapping("/updateTenantInfo")
    public ResponseEntity<Void> updateTenantInfo(@RequestBody Tenant tenant) {
        if(Objects.nonNull(tenant.getId())){
            Date nowDate = new Date();
            tenant.setUpdateDate(nowDate);
            tenant.setStateDate(nowDate);
            tenantService.updateById(tenant);
        }
        return ResponseEntity.ok().build();
    }
    /**
     * 新增 平台租户
     * @param tenant
     * @return
     */
    @PostMapping("/insertTenantInfo")
    public ResponseEntity<Void> insertTenantInfo(@RequestBody Tenant tenant) {
        Date nowDate = new Date();
        String tenantId = UUID.randomUUID().toString().replace("-","");
        tenant.setId(tenantId);
        tenant.setCreateDate(nowDate);
        tenant.setUpdateDate(nowDate);
        tenant.setStateDate(nowDate);
        tenant.setIsLive("0");
        tenant.setIsContract(0);
        tenantService.insertTenantInfo(tenant);
        return ResponseEntity.ok().build();
    }

    @DeleteMapping("/delTenant/{tenantId}")
    public void getTenantList(@PathVariable("tenantId")String tenantId) {
        tenantService.remove(new LambdaUpdateWrapper<Tenant>().eq(Tenant::getId, tenantId));
    }
}

- 效果图片

表格加上序号

在option配置就好
设index属性为true即可，indexLabel设置表格的序号的标题,默认为#

	option:{
          index:true,
          indexLabel:'序号',
          column:[{...}]
         }

etc…
