React Table Row Selection Example > StackOverflow discussion on selecting a row in a React table
Strategy 1: React-table with useRowSelect Hook
When rendering a table using native HTML in a React application, how do we handle the row selection logic? For this scenario, we can employ the useRowSelect hook.
You can learn more about it in the TanStack Table Documentation.
The row selection can be associated with two main methods:
toggleRowSelected(id, value)toggleAllRowsSelected(false)
You can use row.isSelected for conditionally rendering selected states.
Strategy 2: Direct Row Attribute Selection
If the use case does not specifically involve select functionality, you might not want to use the row property directly for selection purposes. Instead, you may require a mapping of rows.
For this, you can define a custom plugin as shown below:
_10// Define your custom hook like this_10const useRowRefs = (hooks) => {_10 hooks.useInstance.push((instance) => {_10 Object.assign(instance, { rowRefs: new Map() });_10 });_10 },_10_10// Add your custom hook to the table hooks_10useRowRefs.pluginName = 'useRowRefs';
It's important to consider type definitions:
_10interface ITableInstanceWithCustomPlugins<D extends object> extends TableInstance<D> {_10 rowRefs: Map<Row['id'], HTMLTableRowElement>_10}
You would inject this into your table instance like so:
_15const TableComponent = ({ columns, data }) => {_15 const tableInstance = useTable(_15 { columns, data },_15 useRowRefs,_15 useRowSelect // if you use additional plugins, they would also be added here_15 );_15_15 const {_15 getTableProps,_15 getTableBodyProps,_15 headerGroups,_15 rows,_15 prepareRow,_15 rowRefs // Be sure to destruct your rowRefs here_15 } = tableInstance as ITableInstanceWithCustomPlugins;
Here's an example of how to utilize it:
_14<tbody {...getTableBodyProps()}>_14 {rows.map((row) => {_14 prepareRow(row);_14 const rowRef = instance.rowRefs[row.id];_14 return (_14 <tr_14 {...row.getRowProps()}_14 ref={(element: HTMLTableRowElement) => {_14 rowRefs.set(row.id, element);_14 }}_14 >_14 );_14 })}_14</tbody>
Both strategies offer robust solutions for handling row selection within React tables. However, the best approach depends on the particular requirements and complexity of your project.
