Material-iu：表格滚动到新页面顶部

Question

我被这个问题困扰了好几天了...

当您单击“下一步”时，我找不到位于新页面顶部的方法，无论我做什么，我总是停留在底部。

我已经检查了 StackOverflow 和 GitHub，我发现这个问题似乎很接近：#9186

我认为使用 ref 和回调是正确的方法，我已经尝试实现它。但是，我总是停留在最后一个元素上，并且无法将顶部滚动到页面之一

我的代码基于自定义分页操作，这是由material-iu制作的表格页面

这是我的代码的示例

function DisplayList(props) {
   var rows = [];
   const data = props.data;
   const tableRef = React.createRef();
   const searchData = props.searchData;
   const setHoverAddress = props.setHoverAddress;

   const classes = useStyles1();

   const [page, setPage] = useState(0);
   const [rowsPerPage, setRowsPerPage] = useState(5);

   const handleChangePage = (event, newPage) => {
       setPage(newPage);   
       if(tableRef.current) {tableRef.current.scrollTop = 0;}
   };

   const handleChangeRowsPerPage = (event) => {
       setRowsPerPage(parseInt(event.target.value, 10));
       setPage(0);
   };


   data.map((result, index) => { // WARNING : slice here which limits the number of results: .slice(0, 5)
       const volulme = Math.round(result.volulme);
       const volulme2 = Math.round(result.volulme2);

       rows.push(
       <div id={index}>
           <ListItem 
           alignItems="flex-start"
           onMouseEnter={e => {
               console.log(index);
           }}
           >
               <Grid container direction="row" spacing={1}>
                   <Grid item xs={5}>

                   {/* <Stage width={150} height={150}>
                       <Layer>
                       <Shape
                           sceneFunc={(context, shape) => {
                           context.beginPath();
                           context.moveTo(20, 10);
                           context.lineTo(120, 80);
                           context.lineTo(120, 140);
                           context.lineTo(22, 140);
                           context.closePath();
                           // (!) Konva specific method, it is very important
                           context.fillStrokeShape(shape);
                           }}
                           fill="#00D2FF"
                           stroke="black"
                           strokeWidth={2}

您向表添加引用并在中使用scrollIntoViewhandleChangePage

工作演示

代码片段

...
const handleChangePage = (event, newPage) => {
    ref.current.scrollIntoView(); //scroll to the beginning of the table
    // window.scrollTo({ top: 0, behavior: 'smooth' }) //scroll to the top of the page
    setPage(newPage);
  };


...

<TableContainer ref={ref} component={Paper}>
        <Table className={classes.table} aria-label="custom pagination table">
          <TableBody>
...
