Do anybody have like this experience? If these were bug, I also want another solution to solve this problem. PLZ help me!
回答1:
Relative positioning inside of <table> tags is not supported. Table rows in fact are simply containers for the bits that show in the GUI (the <td> and <th>). You can style the background color of the table row, but very few other visual aspects extend to this element. Because tables already contain positioning by design it's a waste of time trying to overwrite it. You should either use <div> tags and style them with positioning or use the built-in Table CSS styles.
Additionally check out the answer here: Using Position Relative/Absolute within a TD?
