Both border and height, which you're trying to set, are actually CSS attributes, not HTML.
Set them in the following way:
Or, alternatively, you can use a linked CSS style sheet like this:
#abc1 {
border: 1px;
height: 10px;
}
Just to let you know, setting the height of the table element sets the height of each row, if you want to set the height of the whole table, put the table in div tags and set the height of that element.
