【React】フィルタリングできるテーブルフォームを実装する

2022/11/29に公開

つくったもの

useStateでテーブル全体のstateを管理するテーブルフォームを実装しようとしたのですが、テーブルが大きくなるとフォームの入力に対して再描画が追いつかず使い物になりませんでした。
対応として、stateの管理をuseStateからReact-Hook-Formに移行しました。
ついでにフィルタリング機能もつけました。UIコンポーネントはMaterial-UI(v4)を使用しています。

コード

細かい実装内容は端折って、CSSの設定も割愛します。

Tableの実装

Table.tsx
import InputBase from '@material-ui/core/InputBase';
import FilterListIcon from '@material-ui/icons/FilterList';
import { Popover } from './Popover';
import type { CheckBoxItem } from './CheckBoxItem';
import { Controller, useFieldArray, useForm } from 'react-hook-form';

type FormValues = {
  tableItems: {
    text: string;
    col1: string;
    col2: string;
  }[]
};
const items = [
  {key: 'key_1', label: 'A'},
  {key: 'key_2', label: 'B'},
  {key: 'key_3', label: 'AB'}
]
const initialCheckBoxItems = items.map((item) => ({
  key: item.key,
  label: item.label,
  checked: true,
  disabled: false,
  onStateChange: () => {}
})),

export const Table = () => {
  const { data: tableItems } = useItems();
  const { control } = useForm<FormValues>(
    defaultValues: { tableItems }
  );
  const { fields } = useFieldArray({
    name: 'tableItems',
    control
  });
  
  const [checkBoxItems, setCheckBoxItems] = useState<CheckBoxItem[]>(
    initialCheckBoxItems
  );
  const checkedItems = checkBoxItems
    .filter((item) => item.checked)
    .map((item) => item.label);
  const popoverRef = useRef(null);
  const [anchorEl, setAnchorEl] = useState(null);
  return (
    <>
      <Popover
        initialItems={initialCheckBoxItems}
        items={checkBoxItems}
        setItems={setCheckBoxItems}
        searchPlaceholder={'Search'}
        checkBoxListLabel={'All items'}
        onPopoverClose={() => {
          setAnchorEl(null);
        }}
        anchorEl={anchorEl}
      />
      <Table stickyHeader>
        <TableHead>
          <TableRow>
            <HeaderCell text={'TextInput'} />
            <HeaderCell text={'Column_1'} />
            <HeaderCell
              ref={popoverRef}
              text={'Column_2'}
              badgeCount={checkedItems.length}
              onBadgeClick={() => {}}
              icon={
                <FilterListIcon
                  onClick={() => {
                    setAnchorEl(popoverRef.current);
                  }}
                />
              }
            />
          </TableRow>
        </TableHead>
        <TableBody>
          {fields.map((field, index) => (
            <>
              {checkedItems.includes(field.col2) && (
                <TableRow
                  hover
                  key={field.id}
                >
                  <Controller
                    name={`field.${index}.text`}
                    control={control}
                    render={({ field }) => {
                      return (
                        <InputBase
                          placeholder={'placeholder'}
                          value={field.value}
                          onChange={field.onChange}
                        />
                      );
                    }}
                  />
                  <TextCell text={field.col1} />
                  <TextCell text={fiels.col2} />
                </TableRow>
              )}
            </>
          ))}
        </TableBody>
      </Table>
    </>
  );
};

Popoverの実装

Popover.tsx
import Paper from '@material-ui/core/Paper';
import Grid from '@material-ui/core/Grid';
import Divider from '@material-ui/core/Divider';
import InputBase from '@material-ui/core/InputBase';

import { CheckBoxList } from './CheckBoxList';
import type { CheckBoxItem } from './CheckBoxItem';

type Props = {
  searchPlaceholder: string;
  checkBoxListLabel: string;
  initialItems: CheckBoxItem[];
  items: CheckBoxItem[];
  setItems: React.Dispatch<React.SetStateAction<CheckBoxItem[]>>;
  onPopoverClose: () => void;
  anchorEl: Element | null;
};

const filterItems = (
  items: CheckBoxItem[],
  filterText: string
): CheckBoxItem[] => {
  if (filterText == '') return items;
  return items.filter((item) => item.label.includes(filterText));
};

export const Popover = ({
  searchPlaceholder,
  checkBoxListLabel,
  initialItems,
  items,
  setItems,
  onPopoverClose,
  anchorEl
}: Props) => {
  const [text, setText] = useState('');

  return (
    <MuiPopover
      open={Boolean(anchorEl)}
      anchorEl={anchorEl}
      onClose={onPopoverClose}
      anchorOrigin={{
        vertical: 'bottom',
        horizontal: 'right'
      }}
      transformOrigin={{
        vertical: 'top',
        horizontal: 'left'
      }}
    >
      <Grid>
        <Paper className={classes.searchText}>
          <InputBase
            placeholder={searchPlaceholder}
            text={text}
            onChange={(e) => {
              setText(e.target.value);
              setItems(filterItems(initialItems, e.target.value));
            }}
          />
        </Paper>
        <Divider/>
        <Paper>
          <CheckBoxList
