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 && index === 2 && !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']
]}
