    margin-right:5%;

}

#table1, #table2, #table3, #table4, #table5 {
    display: none;
}

javascript

function show(nr) {
    document.getElementById("table1").style.display="none";
    document.getElementById("table2").style.display="none";
    document.getElementById("table3").style.display="none";
    document.getElementById("table4").style.display="none";
    document.getElementById("table5").style.display="none";
    document.getElementById("table"+nr).style.display="block";
}

我遵循了一个教程，它确实对他有用，但我不知道我做错了什么。我希望有人能帮助我。
