Steps to Reproduce

代码如下:
// import * as ReactVTable from '@visactor/react-vtable';

const { useCallback, useRef, useState } = React;
const { ListTable, ListColumn, Group, Text, Image } = ReactVTable;
const { Avatar, Card, Space, Typography } = ArcoDesign;
const { IconThumbUp, IconShareInternal, IconMore } = ArcoDesignIcon;
const { Meta } = Card;
const { VGroup, VText } = VTable;

const customLayout = (args) => {
const { table, row, col, rect, dataValue, value } = args;
console.log(dataValue, value);
if (!table || row === undefined || col === undefined) {
return null;
}
const { height, width } = rect || table.getCellRect(col, row);
// const record = table.getRecordByCell(col, row);

const cellRange = table.getCellRange(col, row);
let isMergeCell = false;
if (
cellRange.start.col !== cellRange.end.col ||
cellRange.start.row !== cellRange.end.row
) {
isMergeCell = true;
}

const attribute = {
width,
height,
display: 'flex',
flexDirection: 'row',
flexWrap: 'nowrap',
alignItems: 'center',
alignContent: 'center',
}

if (isMergeCell) {
attribute.react = {
element:

return {
renderDefault: false,
rootContainer: (
