我对 webpack 不太熟悉,但我认为它会导致问题。我正在使用反应样板并已将反应表安装为依赖项。添加了代码并显示所有内容,但没有显示 css。如果有人能指出我正确的方向,我将不胜感激!

这就是我将它添加到我的组件的方式

import ReactTable from 'react-table';
import 'react-table/react-table.css';

在我的渲染中,我正在执行以下操作

  <ReactTable
    noDataText="No data available"
    data={this.state.rows}
    columns={[
      {
        columns: this.state.columns
      }
    ]}
  getTdProps={(state, rowInfo, column, instance) => ({
    onMouseEnter: e =>
      console.log('Cell - onMouseEnter', {
        state,
        rowInfo,
        column,
        instance,
        event: e,
      }),
  })}
    defaultPageSize={10}
  className="-striped -highlight"
  />

这就是我的 webpack.config.js 的样子

  resolve: {
    // Allow absolute paths in imports, e.g. import Button from 'components/Button'
    // Keep in sync with .flowconfig and .eslintrc
    modules: ['node_modules', 'src'],
  },

  module: {
    // Make missing exports an error instead of warning
    strictExportPresence: true,

经过几天和几天的反复试验,终于弄明白了。HTH 别人!

在您的组件中,确保您正在从 'isomorphic-style-loader/lib/withStyles' 导入 import withStyles;

然后导入你的模块 css 并给它一个别名。从 'react-datepicker/dist/react-datepicker.css' 导入 rdatescss;

使用以下导出默认值 withStyles(rdatecss)(NAMEOFCOMPONENT); 结束您的组件

要添加多个样式,请使用导出默认值 withStyles(rdatecss, other_style_alias)(NAMEOFCOMPONENT);

这是我的 webpack (4.12.0) 中的规则

我的问题是我没有使用 WithStyle 导入 react-table.css,这就是它不起作用的原因。然后我像看例子一样使用它

import rt from "react-table/react-table.css";



export default compose(
 withStyles(rt),
  connect(
   mapStateToProps,
   {

   },
 ),
)(ApplicationList);
