How to validate a Table based on cells in an order?

You can pass an array to the toContainText() assertion. There's an explanation and examples here: https://playwright.dev/docs/api/class-locatorassertions#locator-assertions-to-contain-text

For table cells, I use a pattern like the following. You don't have to use fixtures and could use the relevant locator in the test.

// In the constructor for a fixture:
this.rows = this.tableContainer.locator('tbody').getByRole('row');

// A convenience method in the fixture:
getRowValues(rowIndex: number) {
    return this.rows.nth(rowIndex).getByRole('cell');
}

// Assertion in a test:
expect(getRowValues(2)).toContainText(['value 1', 'value 2']);

Awesome thank you! Is there something similar to this for retrieving a locator if the values of the cells have data in that order?

The assertion does check order; it will fail if all the values are present but not in the same order. I might be misunderstanding your question, though.

Ah yes, I mean a locator rather than an assertion (aka what would be a way for me to retrieve a row based on the contents (cells that are in order))? If that makes sense
