Question

我有一个独特的情况，我不仅需要标题，还需要第一个行和前三列由于列溢出而在向下和/或向右滚动时保持不变。

Material-UI Table允许我在向下滚动时使标题保持粘性，而不会负面影响溢出，例如以下示例： https://codesandbox.io/s/209r3p0l3y

在我的表中，标题确实粘贴了，但是第一行在向下滚动时必须粘贴，而在向左滚动时则不粘贴（相同的行为）。这是为了使值的溢出保持与标头标签一致。向下和向右滚动时，第一行（尽管不是标题）将与其余几行数据进行比较。同样，前3列也是如此。其他列必须与标题标签和第一行内容保持匹配，但是在完成此操作后，前3列将保持固定在左侧。

重叠多个MUI表是否确实是最好和/或唯一可行的解决方案？我想不出一个更简单的解决方案，想知道是否有人在局限于MUI表或开发独特的表行为时遇到过这种情况。

你可以在没有任何库的情况下制作它。您所要做的就是覆盖它，并根据需要进行设置。

我给你举个例子。

import React from "react";
import {
  makeStyles,
  TableContainer,
  TableBody,
  TableCell,
  TableHead,
  TableRow,
  Table,
  withStyles
} from "@material-ui/core";

const useStyles = makeStyles((theme) => ({
  root: {
    width: "100%",
    marginTop: theme.spacing(3)
  },
  head: {
    backgroundColor: "#fff",
    minWidth: "50px"
  },
  tableContainer: {
    maxHeight: "400px"
  },
  cell: {
    minWidth: "100px"
  }
}));

const StickyTableCell = withStyles((theme) => ({
  head: {
    backgroundColor: theme.palette.common.black,
    color: theme.palette.common.white,
    left: 0,
    position: "sticky",
    zIndex: theme.zIndex.appBar + 2
  },
  body: {
    backgroundColor: "#ddd",
    minWidth: "50px",
    left: 0,
    position: "sticky",
    zIndex: theme.zIndex.appBar + 1
  }
}))(TableCell);

const StyledTableCell = withStyles((theme) => ({
  head: {
    backgroundColor: theme.palette.common.black,
    color: theme.palette.common.white
  },
  body: {
    fontSize: 14
  }
}))(TableCell);

const StyledTableRow = withStyles((theme) => ({
  root: {
    "&:nth-of-type(odd)": {
      backgroundColor: theme.palette.action.hover
    }
  }
}))(TableRow);

const App = () => {
  let id = 0;
  function createData(name, calories, fat, carbs, protein) {
    id += 1;
    return { id, name, calories, fat, carbs, protein };
  }

  const data = [
    createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
    createData("Ice cream sandwich", 237, 9.0, 37, 4.3),
    createData("Eclair", 262, 16.0, 24, 6.0),
    createData("Cupcake", 305, 3.7, 67, 4.3),
    createData("Gingerbread", 356, 16.0, 49, 3.9),
    createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
    createData("Ice cream sandwich", 237, 9.0, 37, 4.3),
    createData("Eclair", 262, 16.0, 24, 6.0),
    createData("Cupcake", 305, 3.7, 67, 4.3),
    createData("Gingerbread", 356, 16.0, 49, 3.9),
    createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
    createData("Ice cream sandwich", 237, 9.0, 37, 4.3),
    createData("Eclair", 262, 16.0, 24, 6.0),
    createData("Cupcake", 305, 3.7, 67, 4.3),
    createData("Gingerbread", 356, 16.0, 49, 3.9),
    createData("Frozen yoghurt", 159, 6.0, 24, 4.0),
    createData("Ice cream sandwich", 237, 9.0, 37, 4.3),
    createData("Eclair", 262, 16.0, 24, 6.0),
    createData("Cupcake", 305, 3.7, 67, 4.3),
    createData("Gingerbread", 356, 16.0, 49, 3.9)
  ];

  const classes = useStyles();

Answer 2

随着时间的流逝，Material-UI版本从v1升级到v4，仍然可以很好地解决这个问题。我现在想为MUI table sticky both row and columns提供解决方案。

我们可以选择使用dx-react-grid-material-ui

具有分页，排序，过滤，分组和编辑功能的Material-UI数据网格

请参阅Material-UI Table Complementary projects的正式文档

我们还可以通过插件 TableFixedColumns

修复列。

一个插件，使您可以将列固定到网格的左侧和右侧。

用法：

import { Grid as GridTable, TableFixedColumns } from '@devexpress/dx-react-grid-material-ui';

<GridTable
  rows={rows}
  columns={columns}
>
  ...
  <TableFixedColumns
    leftColumns={['colNameA', 'colNameB', 'colNameC']}
  />
</GridTable>
