 In fact, the three tables above all have three rows and three columns. The trick to hiding the separator lines lies in the rules. Looking at the source code of these three tables, we can see that there are rules in the <TABLE> tag. It has three parameters (cols, rows, none). When rules=cols, the table will hide the vertical separator lines so that we can only see the rows of the table; when rules=rows, the horizontal separator lines will be hidden so that we can only see the columns of the table; and when rules=none, both the vertical and horizontal separator lines will be hidden. |
