How to add nested table to datatable?

I need to add a nested table to each row of a jquery datatable(using legacy datatables). So, I tried using example from datatables.net for child rows and modifying it to my needs as I need for the child rows to show at all times, rather than on clicking the parent row.Here is the code I am using both to build my inner table and then display it..
function buildInnerTable(){
var keys = Object.keys(reportApp.gridData),
len = keys.length,
j = 0,
prop,
value;
while (j < len) {
prop = keys[j];
value = reportApp.gridData[prop];
detLen = value.detail.length;
var rowVals = [];
for(var i = 0; i < detLen; i++){
tmpRow = "<tr><td>"+value.detail[i].invtid+"</td>"+
"<td>"+value.detail[i].bf+"</td>"+
"<td>"+value.detail[i].qtyship+"</td>"+
"<td>"+value.detail[i].ordqty+"</td>"+
"<td>"+value.detail[i].bf+"</td>"+
"<td>"+value.detail[i].exttreating+"</td>"+
"<td>"+value.detail[i].extpriceinvc+"</td>"+
"<td>"+value.detail[i].misc+"</td>"+
"<td>"+value.detail[i].extother+"</td>"+
"<td>"+value.detail[i].calcext+"</td></tr>";
rowVals.push(tmpRow);
}
setTableRow(rowVals , j);
j += 1;
}
function setTableRow(rowVals , ndx){
$("#gridTbl > tbody > tr:eq("+ ndx+ ")").after("<table><tr><th>InvtID</th>"+
"<th>Clss</th><th>Pieces</th><th>BilQty</th><th>BF</th><th>Treating</th>"+
"<th>Wood</th><th>NEED NAME</th><th>Other</th><th>Misc</th><th>Total</th></tr>"+
rowVals);
But, I am not getting what I need to get. What it looks like is that the datatables adds a new row and then sets the new table inside the first cell on new row. However, when I view source, that isn't what is happening at all. It closes the previous row and then inserts new table...
I am attaching a screenshot. What I need is for the details to show below the main item rows and to be aligned in same way. Any help in where I am wrong will be greatly appreciated.

Ok... Finally figured this out.
In order to make the view show normally, I had to add a new row to the datatable and then, in side that row, add my new table. However, this caused an indexing issue with the table. So, I had to check the index each time before I added new row. I am posting working code in the hope that it will help someone else.
function buildInnerTable(){
var keys = Object.keys(reportApp.gridData),
len = keys.length,
j = 0,
prop,
value;
while (j < len) {
prop = keys[j];
value = reportApp.gridData[prop];
detLen = value.detail.length;
var rowVals = [];
//THIS NEXT LINE IS WHERE I GET MY INDEX...
var ndx = ($("tr:contains("+value.invcnbr+ ")").index());
for(var i = 0; i < detLen; i++){
tmpRow = "<tr><td>"+value.detail[i].invtid+"</td>"+
"<td>"+value.detail[i].bf+"</td>"+
"<td>"+value.detail[i].qtyship+"</td>"+
"<td>"+value.detail[i].ordqty+"</td>"+
"<td>"+value.detail[i].bf+"</td>"+
"<td>"+value.detail[i].exttreating+"</td>"+
"<td>"+value.detail[i].extpriceinvc+"</td>"+
"<td>"+value.detail[i].misc+"</td>"+
"<td>"+value.detail[i].extother+"</td>"+
"<td>"+value.detail[i].calcext+"</td></tr>";
rowVals.push(tmpRow);
}
setTableRow(rowVals,ndx);
}
j += 1;
}
}
function setTableRow(rowVals,ndx){
var outerTbl = $('#gridTbl').DataTable();
var tr = $("#gridTbl > tbody > tr:eq("+ ndx+ ")");
//NOTE HOW I ADD A ROW AND THEN ADD NEW TABLE TO CELL IN THE ROW.
var innerTbl = "<tr><td colspan = 10><table style = 'background- color:#FFFFFF; width:100%; border:1px solid;'><tr><td>InvtID</td>"+
"<td>Clss</td><td>Pieces</td><td>BilQty</td><td>BF</td><td>Treating</td>"+
"<td>Wood</td><td>NEED NAME</td><td>Other</td><td>Misc</td><td>Total</td></tr>"+
rowVals + "</td></tr>";
tr.after(innerTbl).show();
}

Adding Table Header to JSON Table

I am new to Javascript/jQuery and I need some help adding a header to my table. I am getting my data from a JSON array. Here is the code I currently have.
function jsonTable (ChartNum, divclass) {
"use strict";
var output = JSON.parse(document.getElementById(ChartNum).innerHTML);
var table = $('<table></table>');
for (var i=0; i < output.length; i++) {
var tr = $('<tr></tr>');
for (var key in output[i]) {
var td = $('<td></td>');
td.attr('class', key);
td.text(output[i][key]);
tr.append(td);
}
table.append(tr);
}
$(divclass).append(table);
}
jsonTable( 'pdfChart1', '#pdfTable1');
Any help would be really appreciated. Thanks,

Try this:
function jsonTable (ChartNum, divclass) {"use strict";
var output = JSON.parse(document.getElementById(ChartNum).innerHTML);
var table = $('<table></table>');
var trHeader = $('var table = $('<tr><th>Column1</th><th>Column2</th> <th>ColumnsN</th></tr>');
table.append(trHeader);
for (var i=0; i < output.length; i++) {
var tr = $('<tr></tr>');
for (var key in output[i]) {
var td = $('<td></td>');
td.attr('class', key);
td.text(output[i][key]);
tr.append(td);
}
table.append(tr);
}
$(divclass).append(table);
}
jsonTable( 'pdfChart1', '#pdfTable1');
I added variable trHeader where you can add the name of your columns, of course this will only work if your columns are always the same. Or you can get another json with the names of columns and iterate over it to build trHeader in a similar way you build the tds.

How to get th when child td is clicked?

I trying to get the <th> content of the clicked <td> item.
here is the fiddle: http://jsfiddle.net/zrccq447/
the thing is, the <th> can have colspan 2 or 3, this is the point where I am stuck. this is my code
$('#table9').on('click', 'td:not(:nth-child(1))', function () {
var td = $(this);
var clicked_pos = td.index();
var x = $('#headerx9 th:nth-child(' + (clicked_pos) + ')').text();
var xy = td.text();
alert(x);
});
i want x to be the <th> of clicked td. the problem is now that if you click on some td that shares the th with other tds, i am getting the wrong th.
appreciate any help

I've updated your JsFiddle with the answer found here: Finding a colSpan Header for one of the cells or td's is Spans
JsFiddle: http://jsfiddle.net/zrccq447/4/
$('#table9').on('click', 'td:not(:nth-child(1))', function () {
var td = $(this);
var clicked_pos = td.index();
var x = $('#headerx9 th:nth-child(' + thLocator[clicked_pos] + ')').text();
var xy = td.text();
alert(x);
});
var thLocator = [], colCount = 1;
$('#table9').find('tr:first th').each(function () {
for (var i = 0; i < this.colSpan; i++) {
thLocator.push(colCount);
}
colCount++;
});

Following on from my comment you need to sum up the colspans (or default 1) for each TH until you get enough to match the column you desire:
http://jsfiddle.net/TrueBlueAussie/zrccq447/5/
$('#table9').on('click', 'td:not(:nth-child(1))', function () {
var td = $(this);
var clicked_pos = td.index();
var cols = 0;
var $table = td.closest('table');
var $ths = $table.find('tr th');
for (var i = 1; i < $ths.length; i++) {
var $th = $ths.eq(i);
cols += ~~$th.attr('colspan') || 1;
if (cols >= clicked_pos) {
var x = $th.text();
alert(x);
break;
}
}
});
I tried to keep it generic, so it finds the appropriate table and headers on the fly.

One approach is to get store a reference to each TH, in order, in an array and call the text from the array based on the location of the td.
var thholder = $('table th'),
th = [];
for(var i = 0; i < thholder.length; i++) {
var thi = $(thholder[i]);
for(var j = 0; j < (thi.attr('colspan') || 1); j++) {
th.push(thi);
}
}
$('#table9').on('click', 'td:not(:nth-child(1))', function () {
var td = $(this);
var clicked_pos = td.index();
alert(th[clicked_pos].text());
});
http://jsfiddle.net/zrccq447/3/
This code is not optimised, but shows the approach:
Loop through all the TH in the table.
If the TH does not have the attribute 'colspan', then set the attribute to a value of 1.
Create a loop for each value of colspan and save a reference to the current TH in the array.
When you click on a TD, get it's clicked position and retrieve the text of the TH at that position in the array and alert it :)

Separate rows and columns while creating 2d dynamic table

I can't separate row and column td's as I create a 2d table with jquery..
How do I create 10 rows 10 columns 2d table:
what I have done so far:
$(document).ready(function () {
for (var i = 1; i <= 10; i++) {
$('.box').append('<td/>' + '</p>');
for (var j = 1; j <= 10; j++); {
$('.box').append('<td/>');
}
}
});
http://jsfiddle.net/VS37n/
thnx in advance!

You want a table that has 10 columns and 10 rows.
var rows = 10;
var cols = 10;
In an HTML table structure, rows come first in the hierarchy, so, create those first:
$(document).ready(function() {
var rows = 10;
var cols = 10;
var box = $('.box');
for (var r = 0; r < rows; r++) {
var tr = $('<tr>');
//Here we will append the columns to the row before appending it to the box.
box.append(tr);
}
});
The above code only makes 10 rows for us. Now we need to add 10 columns to each row:
$(document).ready(function() {
var rows = 10;
var cols = 10;
var box = $('.box');
for (var r = 0; r < rows; r++) {
var tr = $('<tr>');
for (var c = 0; c < cols; c++) {
tr.append($('<td><p></p></td>')); //Create the table cell, with a p element as in your example, and append it to the row.
}
box.append(tr);
}
});
See this FIDDLE
UPDATE
I just noticed that the jQuery selector from your post selects the <div> element with class .box. You want to add these rows and columns, however, to a <table> element, which doesn't exist. I'd suggest you add a <table> element into your HTML, or, add it with Javascript before adding the rows.
If you can add a <table> element inside of your .box div, then you would just change the following line:
var box = $('.box');
to:
var box = $('.box table:first');
If you can't change the HTML for some reason, then you can dynamically create the table before the rows and columns:
var box = $('<table>').appendTo('.box');

Is this what you're trying to do?
$(document).ready(function () {
var tdHtml = "":
var trHtml = "";
var tableHtml = "";
for(var i=1;i<=10;i++)
{
tdHtml += "<td></td>";
}
for(var j=1;j<=10;j++);
{
trHtml += ("<tr>" + tdHtml + "</tr>");
}
tableHtml = ("<table>" + trHtml + "</table>");
$('.box').innerHtml(tableHtml);
});

You had a ; after your for loop :
for (var j = 1; j <= 10; j++); {
$('.box').append('<td/>');
}
Furthermore, you are not adding <tr> elements.
See the updated fiddle

Combine HTML Table Rows with Javascript

Is there an easy way to combine rows in an HTML table where the first column is the same? I basically have a table set up like:
<table>
<tr><td>test</td><td>12345</td><td>12345</td><tr>
<tr><td>test</td><td>12345</td><td>12345</td><tr>
<tr><td>test2</td><td>12345</td><td>12345</td><tr>
<tr><td>test</td><td>12345</td><td>12345</td><tr>
<tr><td>test2</td><td>12345</td><td>12345</td><tr>
</table>
and I want it to generate:
<table>
<tr><td>test</td><td>37035</td><td>37035</td><tr>
<tr><td>test2</td><td>24690</td><td>24690</td><tr>
</table>

using jQuery:
var map = {};
$('table tr').each(function(){
var $tr = $(this),
cells = $tr.find('td'),
mapTxt = cells.eq(0).text();
if(!map[mapTxt]){
map[mapTxt] = cells;
} else {
for(var i=1, l=cells.length; i<l; i++){
var cell = map[mapTxt].eq(i);
cell.text(parseInt(cell.text()) + parseInt(cells[i].text()));
}
$tr.remove();
}
});
this is a "dumb" script -- no error handling for cases like different number of cells, fields being non-numeric, etc. Add those if necessary.
Also, depending on how it's generated, it's better to do this server-side.

Here's a plain JavaScript version.
window.onload = function() {
var table = document.getElementById('mytable');
var tr = table.getElementsByTagName('tr');
var combined = Array();
for (i = 0; i < tr.length; i++) {
var td = tr[i].getElementsByTagName('td');
var key = td[0].innerText;
if (!combined[key]) {//if not initialised
combined[key] = Array();
for (j = 0; j < td.length - 1; j++) combined[key][j] = 0;
}
for (j = 0; j < td.length - 1; j++)
combined[key][j] += parseInt(td[j + 1].innerText);
}
while (table.hasChildNodes()) table.removeChild(table.lastChild);
var tbody = document.createElement('tbody');//needed for IE
table.appendChild(tbody);
for (var i in combined) {
tr = document.createElement('tr');
tbody.appendChild(tr);
td = document.createElement('td');
td.innerText = i;
tr.appendChild(td);
for (j = 0; j < combined[i].length; j++) {
td = document.createElement('td');
td.innerText = combined[i][j];
tr.appendChild(td);
}
}
}
This will work on tables with any number of rows and any number of cells. I suppose you want to make the sum for every column, that's what this script does.
And as cwolves mentioned, it is more logical to do this serverside. Users that have JS disabled will see the not so clean uncombined table.
