I want to do row virtualization when scrolling (so that data is shown when scrolling)

But when scrolling, now the terrible glitches appear

Tell me what is the problem?

you have to apply the style passed by list for list element rendering which sets height, width and top attributes. you can do as below

const Row = ({ index, style}) => {
      return (
        <Grid container className="table_row" style={style}>
          <Grid item xs={1}>
            <Box className="table_elem name_elem">{data[index].name}</Box>
          </Grid>....…..
