This actually isn't correct. The default state of a table might be to have some columns disabled initially.

web-components/packages/lib/src/async-table/async-table.wc.svelte

Lines 469 to 483 in f4dd2f9

	if (service.getColumnOrder) {
	const pulledHeaders = await service.getColumnOrder(id);
	if (pulledHeaders) {
	headers = headers
	.map((header) => {
	header.disabled = !pulledHeaders.find((it) => it.key === header.key);
	return header;
	})
	.sort((a, b) => {
	const aIndex = pulledHeaders.findIndex((it) => it.key === a.key);
	const bIndex = pulledHeaders.findIndex((it) => it.key === b.key);
	return aIndex - bIndex;
	});
	}
	}

This is where we pull column order from the database and override the default. You need to save a reference of the default and in set it as the current headers in handleReset()
