我正在使用 Facebook 在此处可视化的示例:https ://facebook.github.io/fixed-data-table/example-resize.html

源代码(我使用的是“旧”样式,带有 React.createClass)在这里:https ://github.com/facebook/fixed-data-table/blob/master/examples/old/ResizeExample.js#L35

我已经稍微修改了我的代码。我可以将我的数组解析为单元格,这很好。但是,能够拖动列的整个功能不起作用:鼠标确实正确地执行了拖动列线的动画(如第一个示例中所示),但它永远不会“粘住”。是什么赋予了?

这是一些示例代码。也许我在状态处理方面做错了什么?

var FixedDataTable = require('fixed-data-table');
var React = require('react');

var Column = FixedDataTable.Column;
var Table = FixedDataTable.Table;
var Cell = FixedDataTable.Cell;

var isColumnResizing;

var columnWidths = {
    firstName: 100,
    lastName: 100,
    address: 100,
};
const TextCell = ({rowIndex, data, col, ...props}) => (
    <Cell {...props}>
        {data[rowIndex][col] ? data[rowIndex][col] : " "}
    </Cell>
);


var peopleTable = React.createClass({
    getInitialState() {
        return {
            columnWidths: columnWidths
        }
    },

    _onColumnResizeEndCallback(newColumnWidth, dataKey) {
        var columnWidths = this.state.columnWidths;
        columnWidths[dataKey] = newColumnWidth;
        isColumnResizing = false;
        this.setState({
            columnWidths
        })
    },

    render() {
        if (!this.props.data || !this.props.data.peopleInfo) {
            return <div>No people found</div>;
        }

        var peopleMap = this.props.data.peopleInfo;

        var peopleMapArr = Object.values(peopleMap).map(function(people) {
            return people;
        });

       // Here, it will print the array just fine. So it isn't related to that. 


        return (
            <div>
                <Table
                    height={35 + ((peopleMapArr.length) * 80)}
                    width={750}
                    rowsCount={peopleMapArr.length}
                    rowHeight={80}
                    isColumnResizing={isColumnResizing}
                    onColumnResizeEndCallback={this._onColumnResizeEndCallback}
                    headerHeight={30}
                    {...this.props}>
                    <Column
                        header={<Cell>First Name</Cell>}
                        cell={<TextCell data={peopleMapArr} col="firstName" />}
                        fixed={true}
                        width={columnWidths['firstName']}
                        isResizable={true}
                        minWidth={100}
                        maxWidth={250}
                    />
                    <Column
                        header={<Cell>Last Name</Cell>}
                        cell={<TextCell data={peopleMapArr} col="lastName" />}
                        width={columnWidths['lastName']}
                        isResizable={true}
                        minWidth={100}
                        maxWidth={250}
                    />
                    <Column
                        header={<Cell>Address</Cell>}
                        cell={<TextCell data={peopleMapArr} col="address" />}
                        width={columnWidths['address']}
                        isResizable={true}
                        minWidth={100}
                        maxWidth={250}
                    />
                </Table>
            </div>
        );
    }
});

module.exports = peopleTable;

(这是一个样本)

我已经修改了一些东西,使其能够从我的后端收集数据,但它可以正常工作并正确显示。唯一不起作用的功能是拖动列(如 facebook 调整大小示例)。原因可能是什么?

您需要将dataKey属性添加到每个列或将_onColumnResizeEndCallback函数中的dataKey更改为col
