We can always see such a selector in the Reset Css file:
table{table-collapse:collapse;table-spacing:0}
In my opinion, it is "border-spacing:0"useless, since a property "border-spacing"only works when the value of the property "border-collapse"is equal "separate". When the value "border-collapse"is equal "collapse", it ignores the property "border-spacing".
Is there something wrong with my understanding? Thank.
