About iFrame internal table width and height_html/css_WEB-ITnose

The iFrame is embedded in the web page, and the width and height are fixed. Set a table (table or div) in the iFrame linked web page, and the width and height are both 100%;

But there are differences in the browsers, Chrome meets expectations , the upper part of the table in FF is a certain distance from the border (about 15px), and the table in IE is a certain distance from the right border (about 20px).

How should I set this to remove the extra distance?
