目前,我有一个简单的物料表,如下所示:
<MaterialTable
options={myOptions}
title="MyTitle"
columns={state.columns}
data={state.data}
tableRef={tableRef} // Not working
editable={{
onRowAdd: ...,
onRowDelete: ...,
onRowUpdate: ...
}}
/>;
我要在其中创建一个新的添加按钮(不编辑当前按钮):“条形列”中的每一行都应具有一个自定义的添加按钮。我已经浏览了MaterialTable源代码,但是无法复制用于默认添加按钮的代码:
calculatedProps.actions.push({
icon: calculatedProps.icons.Add,
tooltip: localization.addTooltip,
position: "toolbar",
disabled: !!this.dataManager.lastEditingRow,
onClick: () => {
this.dataManager.changeRowEditing();
this.setState({
...this.dataManager.getRenderState(),
showAddRow: !this.state.showAddRow,
});
},
});
尤其是我无法访问dataManager
变量。
这就是当前表格的样子,我需要在有红色符号的地方添加添加按钮。

我认为这就是您想要的:
操作列代表默认的操作集。我使用自定义列呈现(docs)添加了特定按钮:
//..previous columns definition
{
title: "Custom Add",
field: "internal_action",
editable: false,
render: (rowData) =>
rowData && (
<IconButton
color="secondary"
onClick={() => addActionRef.current.click()}
>
<AddIcon />
</IconButton>
)
}
* 使用rowData作为条件,可防止在填充附加行时呈现。
然后我触发了添加操作,如图here所示:
const MyComponent() {
const addActionRef = React.useRef();
return (
<>
<button onClick={() => addActionRef.current.click()}>
Add new item
</button>
<MaterialTable
//...
components={{
Action: props => {
//If isn't the add action
if (typeof props.action === typeof Function || props.action.tooltip !== 'Add') {
return <MTableAction {...props} />
} else {
return <div ref={addActionRef} onClick={props.action.onClick}/>;
}}
}}
editable={{
onRowAdd: (newData, oldData) => Promise.resolve(); //your callback here
}}
/>
</>
);
}
我扩展了original snippet以便完成加法周期。如果您需要处理不同类型的操作,我认为官方文档的Editable部分会很方便。
希望这对您有用!完整的代码和沙箱here:
