我使用了 prime-react 的可编辑数据表，它可以通过鼠标单击。但问题是制表键不起作用。我想使用制表键启用一个单元格到另一个单元格的可编辑模式。我使用 Prime 反应版本 1.4.0

完整代码如下：-

Dušan 的回答对我有用，但有两个例外：

在onEditorKeyDown而不是

var table = this.dt.container.childNodes[1].childNodes[0].childNodes[1];

利用

let table = this.dt.container.childNodes[0].childNodes[0].childNodes[1];

此外，(event.which === 9)应该使用代替(event.keyCode == 9)并且所有函数都必须绑定在构造函数中：

this.inputTextEditor = this.inputTextEditor.bind(this)
this.xxxEditor = this.xxxEditor.bind(this)
this.onEditorKeyDown = this.onEditorKeyDown.bind(this)

我有一个想法，你可以如何做到这一点：

当您在可编辑单元格中时，您需要拦截 TAB 键，然后模拟单击右侧的下一个单元格，或者，如果当前单元格是最后一个单元格，则单击下一行的第一个单元格。

以下示例中的步骤基于 PrimeReact 的展示案例可编辑页面。您可以针对您的特定情况采用它们。

功能示例

第 1 步：

定义onRowClick处理程序并将其添加到DataTable组件以能够捕获当前单击rowIndex（我们需要知道当前编辑的单元格的行索引是什么）

onRowClick(event) {
    this.rowIndex = event.index;
}
...
<DataTable ref={(el) => this.dt = el} editable={true} onRowClick={(e) => this.onRowClick(e)} ...>

第2步：

为每个列编辑器定义列索引（序号）：第一列索引为 0，第二列索引为 1，等等。例如

vinEditor(props) {
    return this.inputTextEditor(props, 'vin', 0);
}

yearEditor(props) {
    return this.inputTextEditor(props, 'year', 1);
}

brandEditor(props) {
    return this.inputTextEditor(props, 'brand', 2);
}

现在inputTextEditor看起来像这样

inputTextEditor(props, field, columnIndex) {
    return <InputText type="text" value={props.rowData.year}
     onKeyDown={(e) => this.onEditorKeyDown(e, columnIndex)} onChange={(e) => this.onEditorValueChange(props, e.target.value)} />;
}

请注意，我添加了onKeyDown处理程序并将columnIndexarg 传递给它，以便我们可以识别键入某些键的列。

第 3 步：

最后我们可以定义onEditorKeyDown做魔法（查看代码注释以获得更多解释）

onEditorKeyDown(event, columnIndex) {
    console.log("onKeyDown", event);
    console.log("key code", event.keyCode);
    console.log("columnIndex", columnIndex);
    console.log("rowIndex", this.rowIndex);

    //change following 2 constants to to fit your case
    const columnCount = 4;
    const rowCount = 10;

    //check if TAB (key code is 9) is pressed on InputText
    if (event.keyCode == 9) {
        //prevent default behaviour on TAB press
        event.preventDefault();

        //this.dt is reference to DataTable element
        //get reference to `table` node only
        var table = this.dt.container.childNodes[1].childNodes[0].childNodes[1];

        //check if we are not in last column
        if (columnIndex < columnCount - 1) {
            //simulate click on next column
            table.childNodes[this.rowIndex].childNodes[columnIndex + 1].click();
        } else {
            //we are in the last column, check if we are not in last row
            if (this.rowIndex < rowCount - 1) {
                //we are not in the last row
                // select next row
                this.rowIndex += 1;

                //simulate click on first column in next row
                table.childNodes[this.rowIndex].childNodes[0].click();
            }
        }
    }
}
