Auto width doesn't seem to work

[marknuyens]

I was looking for a way to automatically have each cell occupy the width based on its contents (i.e. auto).

While the provided example uses <td _excel-styles='{"width": "auto", "height": 50}'>No need to fill all cells, John Doe</td>, it doesn't seem to have any effect.

What happens when you run php example/example.php? This example contains an auto-width column that works for me.
