I would like to make a form with a div at the top, a div on the left, and a table on the right, as below: Title

My question is: How could I make the table as wide as possible to fully fit in the form? 100px + ??? = 100%

The layout is also applied for mobile (wikiamobile)

For more information, please visit Hero/Info1 to see the forms at the top and the bottom one.
