Assign id's (1,2,..etc) to a dynamic html table

Trying to achieve functionality in the linked picture.
The table grows as users click on the add button. I'm trying to replace the text inside the first column of the newly added td with the length of the table. I'm new to jQuery and not sure how to do that. Any help would be great.

It will be easier to answer you with your code but you can know the added row number with $('#yourTBodyID > tr').length
Have a look to this code :
HTML
<table>
<thead>
<tr>
<th>Zone ID</th>
<th>Zone Description</th>
<th><button onclick="addRow();">Add Row</button></th>
</tr>
</thead>
<tbody id="tableBody">
</tbody>
</table>
JS :
function addRow() {
var rowNum = $('#tableBody > tr').length + 1;
$('#tableBody').append('<tr>'
+ '<td>' + rowNum + '</td>'
+ '<td><input type="text"/></td>'
+ '<td><button>Disable</button></td>'
);
}
jsFiddle
Hope it helps ;)

You'll face a few more problems, more than just showing the number on the recently created tr. As you don't write down any code, I'm note sure at which point of the development you are, or which functionalities have you created already. I'll briefly try to explain how to achieve it, just showing you the path.
Add button should find in the DOM a valid <tr>to .clone(). It could be a "seen tr" or a template one. In the first situation you should clean the information in the input.
Once you have saved that cloned node into a variable, you should prepare it for insertion.
Counting the <tr> lines (it'd help if you have a classname on them) and assign the .length() to the first <td> using .text()
Changing name attribute on the input inside the second <td>tag. Otherwise when the form is sent to the server, you will loose every input with the same name which prior the last one.
On the last <td> tag you have a disabled button. It won't have any attached event on your brand new element. You can attach it here, or if you prefer, you can add the event on the very beginning using something like $('table').on('click','.disable-button',function(e){}). Doing that instead of $(.disable-button).click() will assure you that elements with this class created after DOM .ready()fires up will get this event.
I hope it helped you

Copy HTML Table to Text Box Using JQuery/JS

My problem has left me trying many solutions and stumped for a while now. My problem is exactly this:
There's a HTML table and a button on a page. Upon pressing the button, a script will run, copying the contents of the cells in the table into a text box. Here is the code for the table:
<table>
<tr><th></th><th>Category1</th></tr>
<tr><td>1.</td><td class="rule">Rule1</td></tr>
<tr><td>2.</td><td class="rule">Rule2</td></tr>
<tr><th></th><th>Category2</th></tr>
<tr><td>3.</td><td class="rule">Rule3</td></tr>
<tr><td>4.</td><td class="rule">Rule4</td></tr>
<tr><th></th><th>Category3</th></tr>
<tr><td>5.</td><td class="rule">Rule5 </td></tr>
<tr><td>6.</td><td class="rule">Rule6</td></tr>
<tr><td>7.</td><td class="rule">Rule7</td></tr>
<tr><th></th><th>Category4</th></tr>
<tr><td>8.</td><td class="rule">Rule8</td></tr>
</table>
My first thoughts were to write a script that iterated through the table and copied the contents of each cell (and creating a new line after every 2 cells). I realized very quickly, that I had no idea how to do that. After some searching I was able to come up with a script that clones the table, and it actually works quite well. This code is here:
$("button").click(function () {
$("table").clone().appendTo(".copy");
});
There are two problems that arise from using this method, however. I want plaintext, not a carbon copy of the table. The other problem is that this method only works when I clone the table into a div, it will not work when I try to clone it to a text box.
I've searched for a while for something similar to this and can only find solutions to copying single rows or cells. I had originally started there but couldn't figure out a way to write a loop that started at the beginning of the table and iterated through the entire thing, copying the contents as it iterated row by row (and creating a new line with each new row that it encountered). The loop would obviously end when there were no more rows to iterate through... This all sounds so simple to do, I know there must be a way.
Please Note: This script will be applied to a Site.Master Page so the script must be able to run for a plethora of tables. All of the tables follow the same structure shown above, but some will have more rows than others.
Any ideas? Any help is greatly appreciated.

You could use the .each() JQuery Method:
JS
function cloneTableContents()
{
$("table tr").each(function()
{
$(this).children().each(function()
{
$(".copy").append($(this).text());
});
});
}
JS For All Tables On Page In Order
function cloneTableContents()
{
$("table").each(function()
{
$(this).find("tr").each(function()
{
$(this).children().each(function()
{
$(".copy").append($(this).text()+" ");
});
});
});
}
HTML
<table id="mine">
<tr><th></th>
<th>Category1</th>
</tr>
<tr><td>1.</td><td class="rule">Rule1</td></tr>
<tr><td>2.</td><td class="rule">Rule2</td></tr>
<tr>
<th></th>
<th>Category2</th>
</tr>
<tr><td>3.</td><td class="rule">Rule3</td></tr>
<tr><td>4.</td><td class="rule">Rule4</td></tr>
<tr>
<th></th><th>Category3</th>
</tr>
<tr><td>5.</td><td class="rule">Rule5 </td></tr>
<tr><td>6.</td><td class="rule">Rule6</td></tr>
<tr><td>7.</td><td class="rule">Rule7</td></tr>
<tr>
<th></th><th>Category4</th>
</tr>
<tr><td>8.</td><td class="rule">Rule8</td></tr>
</table>
<textarea class="copy"></textarea>
<button onclick="cloneTableContents('mine','.copy');">Copy</button>

Getting Table Element

I want to get an element for a specific row in my HTML table.
Here is my table.
<tr class="inner2-top">
</tr>
I fill this table using Javascript for the following class:
<td class="ddu-orl">
So far I have around 9 rows. I was wondering how I would get the data for a specific row.
So far I have the following code but it seems to log all of the data for that class. What about for a specific row?
function removeRoute() {
var objectId = $(".inner2-top").find(".ddu-orl").text();
console.log(objectId);
}
I run the following code using the following HTML:
<td class="status1"><img src="images/cross.png" href="#" onclick="removeRoute()" width="12" height="12" alt="cross">

Within an onclick function if you pass this as argument it makes it easy to isolate instance.
<img onclick="removeRoute(this)">
Now you can traverse the DOM from the image. One path is first look up to the closest row, then looking within that row for the element wanted
function removeRoute(elem) {
var objectId = $(elem).closest('tr').find(".ddu-orl").text();
console.log(objectId);
}

Make one div containing a table into two divs containing tables

I have a function that gets raw HTML to output to a table, but I want to take out the first three columns and put them in another div.
I am considering making a div on the page that is hidden, setting this div's html to the raw HTML I get, and then using the selector syntax to strip it into each table's div. Is there a way to do this without the intermediate faux-div to hold the raw HTML?

It all depends out what the "function that gets raw HTML" does. Where is it getting the HTML? If it's in some kind of format other than a rendered node, then you should be able to manipulate it as needed prior to rendering it. If you've got it in a string format (and the markup is valid) jQuery is really good at turning strings into traversible objects. For example:
var xml = '<div><span>hello</span></div>';
console.log($(xml).find('span'));
In FireBug, this displays the span as an object node.

I'm not sure exactly why you'd want to do this, rather than arrange your data server-side, but one approach that works is:
$(document).ready(
function(){
$('table').click(
function(){
$('<table />').appendTo('#newTable').addClass('new');
$('table').eq(0).find('tr td:first-child').each(
function(){
$(this).appendTo('.new').wrap('<tr></tr>');
});
});
});
With the (x)html:
<table>
<tr>
<td>1:1</td>
<td>1:2</td>
<td>1:3</td>
</tr>
<tr>
<td>2:1</td>
<td>2:2</td>
<td>2:3</td>
</tr>
<tr>
<td>3:1</td>
<td>3:2</td>
<td>3:3</td>
</tr>
<tr>
<td>4:1</td>
<td>4:2</td>
<td>4:3</td>
</tr>
</table>
<div id="newTable"></div>
JS Fiddle demo
The demo uses jQuery's click() event, but that's just to show it working interactively; it could certainly be placed straight into the DOM-ready/$(document).ready(function(){/* ... */}); event.
The above code would allow repeated clicks (each time moving the first 'column' into a new table), the edit removes that possibility using jQuery's one(), giving the following jQuery:
$(document).ready(
function(){
$('table').one('click',
function(){
$('<table />').appendTo('#newTable').addClass('new');
$('table').eq(0).find('tr td:first-child').each(
function(){
$(this).appendTo('.new').wrap('<tr></tr>');
});
});
});

Inserting new <TD> elements into a table row

I have created a small application written in XHTML, JavaScript/JQuery and PHP.
The PHP reads and writes to a small SQLite database.
How would I go about inserting <td> cells into a pre-scripted table. The cells would need to be configured using some information from my database. For example, below are two cells with their data retrieved from my database:
Cell One
Starts: 120px;
Finishes: 180px;
Background: Blue;
Cell Two
Starts: 240px;
Finishes: 300px;
Background: Green;
On my table row, it is 500px in width. How would I insert the cells above into the row. In this example, the first cell would start 120px into the row and have a width of 180px. The second cell would start 240px into the row and have a width of 300px.
I just can't seem to work out a way of doing this, any ideas would be very helpful.
Thank you for any input, all is appreciated.
Hunter.

forgive me if this answer is too simplistic but it sounds like you just need to loop through a variable that stores the cells that need to be inserted into a table that already exists.
Then you can dynamically generate the styles of whatever tag you need to edit such as style="<?= background-color:green; ?>"
I'm not exactly sure what you mean by starts and finishes. If your trying do placements then it will be a lot more complicated and you need some sort of position element in your db that can be referenced. But if you just mean height and width then you can also add these elements to the dynamically generate style

Not entirely sure what you're asking, but I'll give it a shot.
var c1 = 'stuff, stuff stuff.' // Your data for cell1
, c2 = 'more stuff.' // Data for cell2
$('table tr:first').append(
// Ugly multiline string
'<td width=120></td>
<td width=60 style="background-color: blue">' + c + '</td>
<td width=60></td>
<td width=60 style="background-color: green">' + c2 + '</td>
<td width=200></td>' // Filler
);

When building the tables, Put html comment tags with parameters so you can scan pre created output and insert where and how you like.
<table>
<!--|str1|2|60|100|--><tr>
<!--|str1td1|--><td width='60'>content row 1</td><!--|etr1td1|-->
<!--|str1td2|--><td width='100'>content row 2</td><!--|etr1td2|-->
</tr><!--|etr1|-->
<!--|str2|2|60|100|--><tr>
<!--|str2td1|--><td width='60'>content row 1</td><!--|etr2td1|-->
<!--|str2td2|--><td width='100'>content row 2</td><!--|etr2td2|-->
</tr><!--|etr2|-->
</table>
Then if you want to go back into your output and insert stuff, just strrpos (php) to the tr you want to edit and gather between comment tags, pharse the pipe seperated fields, you know the first is the id tag, the second is how many td's and the next two can be added to figure the width so far. Then find the tag for the end of the td you want to insert into after. Do your insert (include new tags!). Then go back and re comment the tr info you just read and include new row and information.
After all done and ready to output, go back and remove and the comment tag stuff from output. Or leave it in if you are lazy, it is just html comment stuff that will not be seen but kinda heavy on the text size side.
Sounds more complicated than it is, kind hard to explain but you should know exactly what i mean and the process can be more elaborate or simple to meet your needs.
If this is close to what you need, then hope this helps or ask me more, if not then i am sleepy so please excuse me.
