I think these are the lines where those spaces are added by force

Thank you for using this extension.

This extension respects the Github Flavored Markdown Spec.
In that spec, sample tables have spaces in delimiter row.

@takumisoft68 First, thanks for this great extension! I use it all the time.

I hope you can reconsider this issue. It's true that the sample tables in the spec use spaces in the delimiter row, but that doesn't mean they're required. The spec allows many variations (such as leading/trailing pipes, inconsistent column length, etc.) and so these should be considered matters of personal style. GitHub itself recognizes tables with or without the extra spaces in the delimiter row.

Implementing this would help a lot since other extensions (for other IDEs we use) format tables without the extra spaces.

It would be great to have this option. It can default to off to keep the current behaviour by default
