我正在尝试在材料表中添加一行并且出现错误

提到的示例在材料表文档中

package.json

"dependencies": {
    "@material-ui/core": "^4.1.0",
    "@material-ui/icons": "^4.1.0",
    "classnames": "^2.2.6",
    "material-table": "^1.39.0",
    "react": "^16.8.6",
    "react-dom": "^16.8.6",
    "react-router-dom": "^5.0.1",
    "react-scripts": "3.0.1"
  },

testingList.js

<div className={classes.root}>
  <MaterialTable
    title="Testing"
    icons={tableIcons}
    columns={this.state.columns}
    data={this.state.data}
    editable={{
      onRowAdd: (newData) =>
        new Promise((resolve, reject) => {
          setTimeout(() => {
            {
              const data = this.state.data
              data.push(newData)
              this.setState({ data }, () => resolve())
            }
            resolve()
          }, 1000)
        }),
    }}
  />
</div>

错误：

元素类型无效：应为字符串（用于内置组件）或类/函数（用于复合组件）但得到：未定义。您可能忘记从定义组件的文件中导出组件，或者您可能混淆了默认导入和命名导入。

检查MTableAction.

如果我删除 add 方法，则该功能按预期工作。

如果我删除icons={tableIcons}tableIcons 所在的行，它也可以正常工作

const tableIcons = {
    FirstPage: FirstPage,
    LastPage: LastPage,
    NextPage: ChevronRight,
    PreviousPage: ChevronLeft,
};

我通过降级到版本 1.54.0 解决了它

我有同样的问题，我通过添加解决了它，Actions这样components代码就变成了：

<Table
title="Editable Preview"
columns={this.state.columns}
data={this.state.data}
editable={{
  isEditable: rowData => rowData.name === "a", // only name(a) rows would be editable
  isDeletable: rowData => rowData.name === "b", // only name(a) rows would be deletable

  onRowAdd: newData => new Promise((resolve) => console.log("onrowadd", newData)),
  onRowUpdate: (newData, oldData) => new Promise((resolve) => console.log("onRowUpdate", newData, oldData)),
  onRowDelete: (oldData) => new Promise((resolve) => console.log("onRowDelete", oldData)),
}}
components={{
  Actions: props => (
    <div>
      <IconButton
        onClick={() =>
          this.props.history.push(`/teams/${props.data.uuid}`)
        }
      >
        <EditIcon />
      </IconButton>
      <IconButton
        onClick={() =>
          this.props.history.push(`/teams/${props.data.uuid}`)
        }
      >
        <EditIcon />
      </IconButton>
    </div>
  )
}}
/>

希望这可以帮助！
