有办法判断CellRangeRenderer处理的是多个表格中的哪个表格？
我目前是通过父属性的className来判断的：parent._scrollingContainer.className。
cellRangeRenderer = (props: Object) => {
const renderedCells = defaultCellRangeRenderer(props);
const {
columnStartIndex,
columnStopIndex,
parent,
} = props;
if (parent._scrollingContainer && parent._scrollingContainer.className.includes('grid-header') && columnStopIndex !== 0) {
return [...renderedCells, ...this.props.cachedHeaderElements];
}
return renderedCells;
}
我想知道是否有更简单的方法？

这里有个不那么复杂的办法：
class MyGrid extends Component {
constructor(props) {
super(props);
this.multiGridRef = React.createRef();
}
renderCellRange = props => {
const children = defaultCellRangeRenderer(props);
if (props.parent === this.multiGridRef.current._bottomRightGrid) {
// Operating on bottom right grid
}
return children;
}
render() {
return <MultiGrid ref={this.multiGridRef} cellRangeRenderer={this.renderCellRange} />
}
}
