<script>
function addRow(){
   
    // 插入一行
    myNewRow = document.all.myTable.insertRow();
    var lenRow = document.all.myTable.rows.length; // 計算總行數
   
    if(lenRow > 1){       
        var point = myNewRow.rowIndex;    // 計算當前行位置   
        var lenCol = document.all.myTable.rows(0).cells.length; // 計算每行有幾列
       
        // 插入lenCol個td
            for (i=0; i < lenCol; i++) {
                document.all.myTable.rows(point).insertCell();
                document.all.myTable.rows(point).cells(i).innerHTML = parseFloat(document.all.myTable.rows(point-1).cells(i).innerHTML) + lenCol;
        }
    }else if(lenRow == 1){
        // 原來table是0行,初始化一行
        for(i = 0; i < 10; i++){
            document.all.myTable.rows(0).insertCell();
            document.all.myTable.rows(0).cells(i).innerHTML = i;
        }
    }   
}

function delRow(){
    document.all.myTable.deleteRow();
}
</script>
<a href="javascript: addRow()">增加一行</a>
<a href="javascript: delRow()">減去一行</a>
<table name=myTable border=1 id=myTable>
