Could someone please advise me on how I can customize the length of the rows in a table? I only have two fields in a table, but I would like them to be displayed to the full length of the page.
You can adjust the table size (height and width) by going to source and under the table tag and there you can increase the value of the height and the width. Here is a Screenshot for you reference
I have no idea on how we could change the width of the table in a view since in the view all the display formats come from the theme.
I think a basic page will provide you with what you require but I am not sure if that will be possible for you to use and replace a view with a basic page.
