Question

我正在尝试使用react-table提供的默认加载程序和语义ui-react提供的Spinner。但这似乎不起作用。我维护了三个部分；一个是App，一个是Data Grid，另一个是Spinner。有人可以帮我吗？

应用组件

import * as React from "react";
import { render } from "react-dom";
import DataGrid from "./DataGrid";

interface IProps {}

interface IState {
  data: {}[];
  columns: {}[];
  loading: boolean;
}

class App extends React.Component<IProps, IState> {
  constructor(props: any) {
    super(props);
    this.state = {
      data: [],
      columns: [],
      loading: true
    };
  }

  componentDidMount() {
    this.getData();
    this.getColumns();
  }

  getData = () => {
    let data = [
      { firstName: "Jack", status: "Submitted" },
      { firstName: "Simon", status: "Pending" },
      { firstName: "Pete", status: "Approved" }
    ];
    setTimeout(() => {
      this.setState({ data, loading: false });
    }, 2000);
  };

  getColumns = () => {
    let columns = [
      {
        Header: "First Name",
        accessor: "firstName"
      },
      {
        Header: "Status",
        accessor: "status"
      }
    ];
    this.setState({ columns });
  };

  render() {
    return (
      <>
        <DataGrid
          loading={this.state.loading}
          data={this.state.data}
          columns={this.state.columns}
        />
      </>
    );
  }
}

DataGrid

import * as React from "react";
import ReactTable from "react-table";
import "react-table/react-table.css";
import Spinner from "./Spinner";

interface IProps {
  data: any;
  columns: any;
  loading: boolean;
}

interface IState {}

export default class DataGrid extends React.Component<IProps, IState> {
  render() {
    return (
      <>
        <ReactTable
          loading={this.props.loading}
          data={this.props.data}
          LoadingComponent={Spinner}
          columns={this.props.columns}
        />
      </>
    );
  }
}

Spinner

import { Loader } from "semantic-ui-react";
import * as React from "react";

interface IProps {
  spinnerFlag: boolean;
}

const Spinner: React.FunctionComponent<IProps> = props => {
  return (
    <div>
      <Loader active={props.spinnerFlag}>Loading</Loader>
    </div>
  );
};

export default Spinner;

好的，你缺少什么。

第一件事是，如果您检查沙盒，它的确会在最后显示加载，但存在问题。您需要做两件事

1-给您的微调框适当的样式，使其不会出现在表下方。

2-您需要利用传递给ReactTable组件的加载道具。因为现在您的微调框始终可见，因此不受加载道具的控制

您的微调器组件应使用props.loading而不是props.spinnerFlag，因为这就是传递给ReactTable组件的原因

以此更改Spinner文件

const Spinner: React.FunctionComponent<IProps> = props => {
return props.loading ? (
<div
  style={{
    display: "block",
    position: "absolute",
    left: 0,
    right: 0,
    background: "rgba(255,255,255,0.8)",
    transition: "all .3s ease",
    top: 0,
    bottom: 0,
    textAlign: "center"
  }}
>
  <Loader>Loading</Loader>
</div>
) : null;
};

export default Spinner;

现在您应该可以看到您的装载机了。这是Sandbox

希望这会有所帮助
