border-collapse:collapse添加到表中

The border-collapse CSS property determines whether a table’s borders

are separated or collapsed. In the separated model, adjacent cells

each have their own distinct borders. In the collapsed model, adjacent

table cells share borders.

The separated model is the traditional HTML table border model.

Adjacent cells each have their own distinct borders. The distance

between them given by the border-spacing property.

In the collapsed border model, adjacent table cells share borders. In

that model, the border-style value of inset behaves like groove, and

outset behaves like ridge.
