I know it's not a good pattern to do that, but you will understand why I want to do like that.
I have a HTable
, which use a third-party library (react-table)
const HTable = <T extends object>({ columns, data, tableInstance}: Props<T>) {
const instance: TableInstance<T> = useTable<T> (
// Parameters
)
React.useImperativeHandle(tableInstance, () => instance);
}
Now, I want to control columns visibility from parent. I did:
const Parent = () => {
const [tableInstance, setTableInstance] = React.useState<TableInstance<SaleItem>>();
<Table data={data} columns={columns} tableInstance={(instance) => setTableInstance(instance)}
return tableInstance.columns.map((column) => {
<Toggle active={column.isVisible} onClick={() =>column.toggleHiden()}
}
}
The column hides well, but the state doesn't update and neither does the toggle, and I don't understand why. Could you help me to understand?
EDIT:
Adding a sandbox.
https://codesandbox.io/s/react-table-imperative-ref-forked-dilx3?file=/src/App.js
Please note that I cannot use React.forwardRef, because I use typescript and React.forwardRef doesn't allow generic type like this if I use forwardRef
interface TableProps<T extends object> {
data: T[],
columns: Column<T>[],
tableInstance?: React.RefObject<TableInstance<T>>,
}
Your issue is that react-table
s useTable()
hook always returns the same object as instance
wrapper (the ref never changes). So your parent, is re-setting tableInstance
to the same object - which does not trigger an update. Actually most of the contained values are also memoized. To get it reactive grab the headerGroups
property.
const {
headerGroups,
...otherProperties,
} = instance;
React.useImperativeHandle(
tableInstance,
() => ({ ...properties }), // select properties individually
[headerGroups, ...properties],
);
