How to insert row with attributes using table.insertRow?

Question

I have a html table and insert a new row with table.insertRow(), but the new row doesn't have any attributes or formatting applied. How can I add a row to the table with row formatting?

<INPUT type="button" value="Add Row" onclick="addRow('dataTable')" />

<INPUT type="button" value="Delete Row" onclick="deleteRow('dataTable')" />

<TABLE id="dataTable" width="100%" align="center">
    <TR align="center" border="1">
        <TH></TH>
        <TH>ID </TH>
        <TH>Name</TH>
        <TH>Status</TH>
    </TR>
    <TR align="center">
        <TD><INPUT type="checkbox" name="chk"/></TD>
        <TD> 1 </TD>
        <TD> <INPUT type="text" value="Submission 1" /> </TD>
    <TD>Working version</TD>
    </TR>
</TABLE>

<script type="text/javascript">
    function addRow(tableID) {

        var table = document.getElementById(tableID);

        var rowCount = table.rows.length;
        var row = table.insertRow(rowCount);

        var cell1 = row.insertCell(0);
        var element1 = document.createElement("input");
        element1.type = "checkbox";
        cell1.appendChild(element1);

        var cell2 = row.insertCell(1);
        cell2.innerHTML = rowCount;

        var cell3 = row.insertCell(2);
        var element2 = document.createElement("input");
        element2.type = "text";
        cell3.appendChild(element2);

    }

    function deleteRow(tableID) {
        try {
        var table = document.getElementById(tableID);
        var rowCount = table.rows.length;

        for(var i=0; i<rowCount; i++) {
            var row = table.rows[i];
            var chkbox = row.cells[0].childNodes[0];
            if(null != chkbox && true == chkbox.checked) {
                table.deleteRow(i);
                rowCount--;
                i--;
            }
        }
        }catch(e) {
            alert(e);
        }
    }

</script>

I found it's better to use jquery to add rows to tables

        $('#dataTable tr:last').after('<TR align="center"><TD><INPUT type="checkbox" name="chk"/></TD><TD>'+ rowCount + '</TD><TD> <INPUT type="text" value="Submission 1" /> </TD><TD>Working version</TD></TR>');

To set the class name for a tablerow you simply need to edit the className attribute as done below

<script>
var table = document.getElementById("tableID");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount-1);
row.className = "rowdiv";
</script>

Considering insertRow() is usually where you put the index, and var row = table.insertRow(rowCount); is used here, how can you move it to specific part of the table?

If using Javascript ES6, you can use the setAtribute method to set an element class name, id name, or style. Below is an example:

<script>
var table = document.getElementById("yourTableIDName");
var rowCount = table.rows.length-1;
var row = table.insertRow(rowCount);
row.setAttribute('class', 'yourClassName');
</script>
