Material-table: How to change selected rows from outside of component?

[Buuntu]

I'm unable to find anything in the documentation about how to do this, I imagine it's using the tableRef property but I don't know what properties that contains that would be able to change the selected rows. I am using a table with selection enabled, basically I want somewhere outside of this component to handle the selected rows as well (like remove certain rows).

<MaterialTable
    columns={columns}
    data={files}
    title="Table"
    tableRef={tableRef}
    options={{
      selection: true,
    }}
>

const removeSelectedRow = (idx: number) => {
// what goes here?
tableRef.current.removeSelectedRow(idx);
}

I need this so bad!

I think I figured out how to solve it using tableRef, although it's not great:

const tableRef = useRef<any>(); // not sure if there's a better type for this

const removeFromChecked = (idx: number) => {
    if (!tableRef) {
      return;
    }

    tableRef.current.dataManager.changeRowSelected(false, [idx]);
};

return <MaterialTable
  tableRef={tableRef}
  data={data}
  columns={columns}
/>;

This seems like a common enough use case to be in the docs, I think.

I don't get why this feature hasn't been implemented yet. Programmatically selected rows is a common use case, i.e. when table being used in forms.

Trying to use the reverse of this by taking in URL query params and initially selecting a row based on the params. Tried using the tableRef technique shown by @Buuntu, but doing that makes it so you can't deselect the row from the table. This would be a good feature to add.

Edit: Looking at my code more, I think my problem actually had to do with the useEffect hook I was using. The conditional I had created to select an item made it so deselecting all items would run the hook again and thus take the params from the URL to select the item again.
