这是HTML(超文本标记语言)中的表格属性。
- border="1" 表示表格的边框厚度为1个像素(px)。

As an AI language model, I don't have personal opinions or feelings, but I can provide you with information about the term "null".
"Null" is a term used in computer programming and databases to indicate that a variable or field has no value assigned to it. In programming languages, null is typically represented by a special keyword or symbol, such as "null" or "nil". In database systems, null indicates a missing or unknown value in a table column.
In mathematics, null can refer to the null set, which is the set containing no elements. This set is denoted by the symbol ∅ or {}.
Overall, the term "null" is used to represent a lack of value, information or existence.
