How to get the selected row value of table table in layui

layui.table.checkStatus('tableId');

let data = layui.table.checkStatus('tableId').data;

let index = layui.table.checkStatus('tableId').index;

layui.use('table', function () {
  var table = layui.table;

  // 获取表格实例
  let instance = table.render({
    elem: '#test-table',
    data: [{ id: 1, name: 'John Doe' }, { id: 2, name: 'Jane Doe' }],
    cols: [[{ type: 'checkbox' }, { field: 'id', title: 'ID' }, { field: 'name', title: '姓名' }]]
