How can I do this with Gravity Forms

If you really want all the table structure around there, you'd have to make extensive use of the HTML fields but I really wouldn't recommend it. You could always try to position the individual list items that contain the form fields with CSS and style them to emulate a table, but that's going to be a ton of work too. You CAN do it if you want to invest the time and have the CSS moxy to get it done.

My suggestion would to make a form that looks like an actual web form and not a copy of a print form. You can make use of the built in CSS Ready Classes to create column style layouts where it makes sense and to save some vertical space. I think you'll find that will be easier for people to use in the long run as well.

If all that's too much for you, you might want to consider hiring a professional developer to help with the customizations.

You can style the multi-page steps to look like tabs, but they don't have any hyperlinks are intended to be step indicators and not a navigation element.

You would have to write and implement some custom code to actually make tabs that allowed you to move back and forth through the form.
