Judging from the results of running the above code: the two tables only have different cellpadding code values. In the first table, the words "I am a happy cell table" The word "I am a happy cell table" in the second table is far away from the cell where it is located. That is because cellpadding="0" is set. , that's because cellpadding="20", that is to say, the distance between "I am a happy cell table" and the border of the cell where it is located is 20 pixels. Simply put, the value of cellpadding is equal to how much blank space the cells in the table retain inward from their own boundaries. The elements in the cell will never enter those blank spaces. ||Note that the cellpadding attribute is used to specify the size of the blank distance between the cell content and the cell boundary. The parameter value of this attribute is also a number, which represents the number of pixels occupied by the height of the blank distance between the cell content and the upper and lower borders and the number of pixels occupied by the width of the blank distance between the cell content and the left and right borders.
