Add table row in jQuery

Question

What is the best method in jQuery to add an additional row to a table as the last row?

Is this acceptable?

$(\'#myTable\').append(\'

        

Answer 1

What if you had a <tbody> and a <tfoot>?

Such as:

<table>
    <tbody>
        <tr><td>Foo</td></tr>
    </tbody>
    <tfoot>
        <tr><td>footer information</td></tr>
    </tfoot>
</table>

Then it would insert your new row in the footer - not to the body.

Hence the best solution is to include a <tbody> tag and use .append, rather than .after.

$("#myTable > tbody").append("<tr><td>row content</td></tr>");

Answer 2

Neil's answer is by far the best one. However things get messy really fast. My suggestion would be to use variables to store elements and append them to the DOM hierarchy.

HTML

<table id="tableID">
    <tbody>
    </tbody>
</table>

JAVASCRIPT

// Reference to the table body
var body = $("#tableID").find('tbody');

// Create a new row element
var row = $('<tr>');

// Create a new column element
var column = $('<td>');

// Create a new image element
var image = $('<img>');
image.attr('src', 'img.png');
image.text('Image cell');

// Append the image to the column element
column.append(image);
// Append the column to the row element
row.append(column);
// Append the row to the table body
body.append(row);

Answer 3

In my opinion the fastest and clear way is

//Try to get tbody first with jquery children. works faster!
var tbody = $('#myTable').children('tbody');

//Then if no tbody just select your table 
var table = tbody.length ? tbody : $('#myTable');

//Add row
table.append('<tr><td>hello></td></tr>');

here is demo Fiddle

Also I can recommend a small function to make more html changes

//Compose template string
String.prototype.compose = (function (){
var re = /\{{(.+?)\}}/g;
return function (o){
        return this.replace(re, function (_, k){
            return typeof o[k] != 'undefined' ? o[k] : '';
        });
    }
}());

If you use my string composer you can do this like

var tbody = $('#myTable').children('tbody');
var table = tbody.length ? tbody : $('#myTable');
var row = '<tr>'+
    '<td>{{id}}</td>'+
    '<td>{{name}}</td>'+
    '<td>{{phone}}</td>'+
'</tr>';


//Add row
table.append(row.compose({
    'id': 3,
    'name': 'Lee',
    'phone': '123 456 789'
}));

Answer 4

My solution:

//Adds a new table row
$.fn.addNewRow = function (rowId) {
    $(this).find('tbody').append('<tr id="' + rowId + '"> </tr>');
};

usage:

$('#Table').addNewRow(id1);

Answer 5

To add a good example on the topic, here is working solution if you need to add a row at specific position.

The extra row is added after the 5th row, or at the end of the table if there are less then 5 rows.

var ninja_row = $('#banner_holder').find('tr');

if( $('#my_table tbody tr').length > 5){
    $('#my_table tbody tr').filter(':nth-child(5)').after(ninja_row);
}else{
    $('#my_table tr:last').after(ninja_row);
}

I put the content on a ready (hidden) container below the table ..so if you(or the designer) have to change it is not required to edit the JS.

<table id="banner_holder" style="display:none;"> 
    <tr>
        <td colspan="3">
            <div class="wide-banner"></div>
        </td>   
    </tr> 
</table>

Answer 6

<table id=myTable>
    <tr><td></td></tr>
    <style="height=0px;" tfoot></tfoot>
</table>

You can cache the footer variable and reduce access to DOM (Note: may be it will be better to use a fake row instead of footer).

var footer = $("#mytable tfoot")
footer.before("<tr><td></td></tr>")
