Data Tables

Data tables display sets of data.

• Module @rmwc/data-table
• Import styles:
  • Using CSS Loader
    • import '@rmwc/data-table/styles';
  • Or include stylesheets
    • '@material/data-table/dist/mdc.data-table.css'
    • '@rmwc/data-table/data-table.css'
    • '@rmwc/icon/icon.css'

Standard Table

The DataTable components are intended to be flexible, properly styled, Material compliant HTML tables. Because of the complexities of working with datasets (especially large ones), the DataTable component DOES NOT handle pagination, data fetching, sorting, or performance of long lists.

function Example() {
  const [sortDir, setSortDir] = React.useState(null);
  const items = [
    { item: 'Cookies', quantity: 25, price: '$2.90' },
    { item: 'Pizza', quantity: 50, price: '$1.25' },
    { item: 'Icecream', quantity: 10, price: '$2.35' }
  ];
  const sortedItems =
    sortDir === 1
      ? items.sort((a, b) => a.quantity - b.quantity)
      : items.sort((a, b) => b.quantity - a.quantity);
  return (
    <DataTable>
      <DataTableContent>
        <DataTableHead>
          <DataTableRow>
            <DataTableHeadCell>Item</DataTableHeadCell>
            <DataTableHeadCell
              alignEnd
              sort={sortDir}
              onSortChange={(sortDir) => {
                setSortDir(sortDir);
                console.log(sortDir);
              }}
            >
              Quantity (Click Me)
            </DataTableHeadCell>
            <DataTableHeadCell alignEnd>Unit price</DataTableHeadCell>
          </DataTableRow>
        </DataTableHead>
        <DataTableBody>
          {sortedItems.map((item) => (
            <DataTableRow key={item.item}>
              <DataTableCell>{item.item}</DataTableCell>
              <DataTableCell alignEnd>{item.quantity}</DataTableCell>
              <DataTableCell alignEnd>{item.price}</DataTableCell>
            </DataTableRow>
          ))}
        </DataTableBody>
      </DataTableContent>
    </DataTable>
  );
}

Scrollable / Sticky Rows and Columns

You can set a fixed sized for your table container to make it scrollable. Additionally, you can specify stickyRows or stickyColumns to affix rows or columns. Currently, only 1 row / column is supported but more may be supported in a future release.

function Example() {
  const [rows, setRows] = React.useState(0);
  const [cols, setCols] = React.useState(0);
  const sampleColumns = Array(7).fill(undefined);
  const sampleRows = Array(50).fill(undefined);

  return (
    <>
      <DataTable
        style={{ height: '300px', width: '375px' }}
        stickyRows={rows}
        stickyColumns={cols}
      >
        <DataTableContent>
          <DataTableHead>
            <DataTableRow>
              <DataTableHeadCell>Label</DataTableHeadCell>
              {sampleColumns.map((v, i) => (
                <DataTableHeadCell key={i}>Header</DataTableHeadCell>
              ))}
            </DataTableRow>
          </DataTableHead>
          <DataTableBody>
            {sampleRows.map((v, i) => (
              <DataTableRow key={i}>
                <DataTableCell>Label</DataTableCell>
                <DataTableCell>R{i} C1</DataTableCell>
                <DataTableCell>R{i} C2</DataTableCell>
                <DataTableCell>R{i} C3</DataTableCell>
                <DataTableCell>R{i} C4</DataTableCell>
                <DataTableCell>R{i} C5</DataTableCell>
                <DataTableCell>R{i} C6</DataTableCell>
                <DataTableCell>R{i} C7</DataTableCell>
              </DataTableRow>
            ))}
          </DataTableBody>
        </DataTableContent>
      </DataTable>

      <div className="doc-controls">
        <Select
          label="Sticky Rows"
          options={['0', '1']}
          value={String(rows)}
          onChange={(evt) => setRows(Number(evt.currentTarget.value))}
        />
        <Select
          label="Sticky Cols"
          options={['0', '1']}
          value={String(cols)}
          onChange={(evt) => setCols(Number(evt.currentTarget.value))}
        />
      </div>
    </>
  );
}

Form Controls

DataTables play nice with the rest of the RMWC form controls. You are responsible for scripting your own selection behavior.

function Example() {
  const [checked, setChecked] = React.useState({});
  const sampleRows = new Array(5).fill(undefined);

  return (
    <DataTable>
      <DataTableContent>
        <DataTableHead>
          <DataTableRow>
            <DataTableHeadCell hasFormControl>
              <Checkbox />
            </DataTableHeadCell>
            <DataTableHeadCell>Label</DataTableHeadCell>
            <DataTableHeadCell>Header</DataTableHeadCell>
            <DataTableHeadCell>Header</DataTableHeadCell>
            <DataTableHeadCell>Toggle</DataTableHeadCell>
          </DataTableRow>
        </DataTableHead>
        <DataTableBody>
          {sampleRows.map((v, i) => (
            <DataTableRow key={i} selected={checked[i]}>
              <DataTableCell hasFormControl>
                <Checkbox
                  checked={checked[i]}
                  onChange={(evt) => {
                    checked[i] = evt.currentTarget.checked;
                    setChecked({ ...checked });
                  }}
                />
              </DataTableCell>
              <DataTableCell>Label</DataTableCell>
              <DataTableCell>
                <Select
                  placeholder="--Select--"
                  options={['Cookies', 'Pizza', 'Icecream']}
                />
              </DataTableCell>
              <DataTableCell>R{i} C3</DataTableCell>
              <DataTableCell>
                <Switch />
              </DataTableCell>
            </DataTableRow>
          ))}
        </DataTableBody>
      </DataTableContent>
    </DataTable>
  );
}

Simplified Usage

If you just need to throw a table on the screen, you can pass an array of data to SimpleDataTable.

<SimpleDataTable
  getRowProps={(row) => {
    return row[1] > 100 ? { activated: true } : {};
  }}
  getCellProps={(cell, index, isHead) => {
    const props = { isNumeric: index > 0, style: undefined };

    return !isHead &amp;&amp; index === 2 &amp;&amp; !cell.includes('$')
      ? { ...props, style: { color: 'red' } }
      : props;
  }}
  headers={[['Item', 'Quantity', 'Value']]}
  data={[
    ['Cookies', 25, '$12.40'],
    ['Pizza', 11, '$10.43'],
    ['Icecream', 3, '1.43'],
    ['Candy', 72, '$22.45'],
    ['Cakes', 101, '$215.05'],
    ['Muffins', 3, '$5.97']
  ]}
/>
