This basically just checks if it's a range selection located inside of a table and if all of the cells are selected. If so, it converts the range selection to a grid selection.

const {grid} = tableSelection;

if (
selection.getNodes().filter($isTableCellNode).length ===
grid.rows * grid.columns
) {
const gridSelection = DEPRECATED_$createGridSelection();
const tableKey = tableNode.getKey();
const tableFirstDescendant = tableNode.getFirstDescendant();
const tableLastDescendant = tableNode.getLastDescendant();

const firstCell =
tableFirstDescendant &&
$findMatchingParent(tableFirstDescendant, $isTableCellNode);

const lastCell =
tableLastDescendant &&
$findMatchingParent(tableLastDescendant, $isTableCellNode);
