Tips for setting HTML table borders

For many beginners of HTML, table <Table> is the most commonly used tag, but many beginners do not know much about table border control.

Generally, when using a table, we always give it a border attribute, for example, <Table border = "1">. The effect is as follows:

ID	Name	Gender
1001	Mike	Male

We can see that the border of the table seems very wide. Of course, the "wide" here is definitely not the width of the table border. We can see that there is a gap between the widths. Therefore, you only need to modify the cellspacing attribute of the table, that is, <Table border = "1px" cellspacing = "0px">. The effect is as follows:

ID	Name	Gender
1001	Mike	Male

However, it seems that the width is not as we think: only the width of one pixel is actually the width of two pixels. Why, this is because the border between <TD> does not overlap. Modify the border-collapse attribute of the table,

That is, <Table border = "1px" cellspacing = "0px" style = "border-collapse: collapse">

ID	Name	Gender
1001	Mike	Male

Add a color to the table. <Table border = "1px" bordercolor = "#000000" cellspacing = "0px" style = "border-collapse: collapse">

ID	Name	Gender
1001	Mike	Male
