For everyone who comes across this. You can also inject the text alignment within the "Create HTML Table" action, if you want to align each column individually:

<div style="text-align: left">YOUR REFERENCE</div>
Same as for the other solutions, you need to replace the special characters to make sure you get proper HTML code:

replace(replace(replace(replace(body('Create_HTML_table'), '<', '<'), '>', '>'), '"', '"'), '^', ' ')
Bonus tip: As you can see I added a "^" in the table headers, which I then replace to allow for spaces in the header titles.
