title: '',
width: 60,
headerType: 'checkbox',
cellType: 'checkbox',
},
{
field: 'productName',
title: 'productName',
width: 120
},
];
const option = {
records,
columns
};
const tableInstance = new VTable.ListTable(document.getElementById(CONTAINER_ID), option);
window['tableInstance'] = tableInstance;

setTimeout(() => {
const info = tableInstance.getCheckboxState('isCheck');
const infos = tableInstance.getCheckboxState();
console.log(info, infos,'1111111')
