Select and sort a column in a table using Javascript

I want to select a particular column of a table and sort it accordingly using Javascript (No frameworks or plugins). Could anyone help me regarding this?
<table>
<thead>
<tr>
<td>Col1</td>
<td>Col2</td>
<td>Col3</td>
<td>Col4</td>
</tr>
</thead>
<tbody>
<tr>
<td>Data11</td>
<td>Data23</td>
<td>Data53</td>
<td>Data45</td>
</tr>
<tr>
<td>Data81</td>
<td>Data42</td>
<td>Data33</td>
<td>Data4854</td>
</tr>
<tr>
<td>Data84681</td>
<td>Data452</td>
<td>Data354</td>
<td>Data448</td>
</tr>
<tr>
<td>Data1846</td>
<td>Data25635</td>
<td>Data3232</td>
<td>Data44378</td>
</tr>
</tbody>
</table>

function sortTableByColumn(tableId,columnNumber) { // (string,integer)
var tableElement=document.getElementById(tableId);
[].slice.call(tableElement.tBodies[0].rows).sort(function(a, b) {
return (
a.cells[columnNumber-1].textContent<b.cells[columnNumber-1].textContent?-1:
a.cells[columnNumber-1].textContent>b.cells[columnNumber-1].textContent?1:
0);
}).forEach(function(val, index) {
tableElement.tBodies[0].appendChild(val);
});
}
In your page, add id to the table tag:
<table id="myTable">
From javascript, use:
sortTableByColumn("myTable",3);
tBodies[0] is used because there can be many. In your example there is only one.
If we have var arr=[123,456,789], [].slice.call(arr) returns a copy of arr.
We're feeding it the html-rows-collection, found in tBodies[0] of tableElement.
Then, we sort that array with an inline function that compares two array elements, here: rows (<tr>).
Using cells[columnNumber] we access the <td>s, and textContent to access the text content. I've used columnNumber-1 so you can enter 3 for third column instead of 2, because the index of first element of an array (column 1) is 0...
The forEach goes through the elements of the array, which is by now in order, and appendChild row to the tBody. Because it already exist, it just moves it to the end: moving the lowest value to the end, then moving the second lowest to the (new) end, until it ends with the highest value, at the end.
I hope this is what you want. If so, enjoy!

Try using datatables you can get it from http://datatables.net its reallt easy to use. depends on jQuery
$("table").dataTable();
boom! and its done.

DataTables: TypeError: i is undefined

I have a table like the following
the table as rowspans because for some users I need to have 2 lines (Like you see at column 'D')
I am trying to use datatables:
<table class="table table-bordered table-hover table-striped" id="myTable">
(...)
</table>
And I call this at the begining of the code:
<script>
$( document ).ready(function() {
$('#myTable').DataTable();
});
</script>
But I have this error:
TypeError: i is undefined
And the table is not like a datatable type!
Maybe it doesn't work with rowspans?
Any idea??

FWIW you can also get this error if you don't have the same number of <td></td> elements in every row. Make sure you aren't adding any rows with nav buttons or links or anything like that that may not be formatted the same way as the other rows.

jQuery DataTables plug-in doesn't support ROWSPAN attribute by default. However there is a RowsGroup plugin for jQuery DataTables that groups cells together to make them look like as if ROWSPAN attribute is used.
See this example for code and demonstration.
See jQuery DataTables – ROWSPAN in table body TBODY for more details.

For future referer.
It is because you are using Rowspan or colspan which is not supportable.
If you want to use colspan you can use it outside </tbody>.
Thanks.

This problem happens if your table is not well formed, for example you should have
<table>
<thead>
<th>
<tbody>
<tr>
<td>
And then the id of the table should not overlap with id of any thing else on the same page. Other wise you will get errors like i is udefined or c is undefined.

I'd say your table is not a data table because you have undefined data and the 'i' referred to is the internal iterator of the DataTable loop, the use of rowspans is the problem - I would redesign your table to have an entire row for each piece of data (in your example 250 would require an entire row with duplicate values for all other columns except D) - it is wholly possible to use css to hide values that are duplicated for the same visual effect, this would allow datatable filtering to still work on those rows (although you may need some hooks to reveal hidden data when these 'extra' rows are filtered).

I was facing the same issue. The main reason for the error is due to using the colspan & rowspan. Because the jQuery DataTables plug-in does not support them and hence causing the error.
TypeError: i is undefined
So, If you are using any colspan or rowspan within any <tr></tr> inside the <tbody></tbody> then make sure that each <tr></tr> having the same no of <td></td> for each row. If not, then repeat the <td style='display:none'></td> to match the same no e.g
<table border='1' cellspacing='2'>
<thead>
<tr>
<td>A</td>
<td>B</td>
<td>C</td>
</tr>
</thead>
<tbody>
<tr>
<td rowspan="2">1</td>
<td rowspan="2">name</td>
<td>200</td>
<td style='display:none'></td>
<td style='display:none'></td>
</tr>
<tr>
<td >300</td>
<td style='display:none'></td>
<td style='display:none'></td>
</tr>
</tbody>
</table>
I think by following the above suggestion will help you sure.

export html table to Excel numbers became dates

I want to export a html table to Excel.
Table:
<div id="table">
<table>
<thead>
<tr>
<th>Column</th>
<th>Column</th>
</tr>
</thead>
<tbody id="tabbodyExp">
<tr>
<th>2.5</th>
<th>2.6</th>
</tr>
</tbody>
</table>
</div>
Script:
$("#btnExport").click(function (e) {
window.open('data:application/vnd.ms-excel,' + $('#table').html());
e.preventDefault();
});
But excel is turning all numbers that are written like that "2.5" to Dates. Is there a way to stop that or do I have to write all number like that "2,5".

I found the answer on scunliffe's post here: Format HTML table cell so that Excel formats as text? As per that post, you can apply this special CSS property to the table cell and Excel will start treating the value as a string instead of formatting it as number (hopefully this works the same for your Dates):
mso-number-format:"\#"; /*force text*/

I know this is a old question but i will add my answer as it can help to other users that try to use numbers in excel.
In my case mso-number-format:"\#"; does not work so i use vnd.ms-excel.numberformat:0.0;
Example:
<th style="vnd.ms-excel.numberformat:0.0;">2.5</th>
or
<th style="vnd.ms-excel.numberformat:0.0;">2,5</th>

Get key values and create a table header

I have an angularjs application that basically takes JSON and creates a HTML table, with the keys in the <thead> and the values as table rows.
I have a JSFiddle here where I take the JSON and create table rows based on the values. But I can't figure out how to take the keys and align them with the values as table headers.
My angular code:
<tr ng-repeat='row in rows'>
<td ng-repeat="data in row.data">
{{data}}
</td>
</tr>
and:
function TableController($scope){
$scope.rows = data;
}

Take a look here: How can I iterate over the keys, value in ng-repeat in angular
<tr ng-repeat="(key, value) in data">
<td> {{key}} </td> <td> {{ value }} </td>
</tr>
====EDIT==== Since you're doing it all in the same table, you'll need to do it a different way. You need to separate the header values while you're still in the controller so that you have a clean way to iterate over your list. Here the fiddle: http://jsfiddle.net/L93v5/1/
Your revised way looks bad because there are two different tables and the cell sizes are different. This will keep it all in the same table and make things a bit cleaner.

sum of columns using ng-table angular

I am using angular/ng-table to plot numerical data in tabular form.
I am not able to figure out how to bring in a row at the end of my table which shows sum of all the values of each column.
I can compute the data on the server side and present it in the UI.
But is there a way to achieve this in ng-table/ng-grid?
Any help will be appreciated.
thanks

You mean something like this?
<table ng:init="stuff={items:[{description:'gadget', cost:99},{description:'thing', cost:101} ]}">
<tr>
<th>Description</th>
<th>Cost</th>
</tr>
<tr ng:repeat="item in stuff.items">
<td>{{item.description}}</td>
<td>{{item.cost}}</td>
</tr>
<tr>
<td></td>
<td>{{stuff.items.$sum('cost')}}</td>
</tr>
