How table thin borders are implemented

Mode 1

Set the border of the border=0,cellspacing=1, set the background color of the table to the desired border color, and then set all the TD background color is white, so the thin border is revealed.

Mode 2

Set border=0 , then via CSS, add 1px border-top,border-left to table, then set all TD Border-right,border-bottom, This will also achieve the desired effect.

Mode 3

Set the table's CSS to {border-collapse:collapse;border:none;}, then set the TD css to {border:solid #000 1px;}

Of these, Border-collapse has two properties, separate and collapse

1, separate is the default property, the table border default has a gap of 1px

2, collapse, is to remove the gap of the table border, so that the table TD border assignment will not produce a double wireframe
