Make packery.js rows equal height

I'm trying to implement packery.js to display a grid of various elements which works so far. The elements height varies, so when a single element in the grid is larger than others, elements from the next row 'dock' onto elements from the first row.
Is it possible that packery makes the rows height equal to the largest row-element?

How can I find the height of a dynamically created table row element with no height set?

I have two tables adjacent to each other both being populated dynamically in C#, I want both of these two tables to have the corresponding row height be exactly the same depending on what the first tables row height is (no specific height has been set, just needs to fit text in).
I have tried various ways of getting the height in C#, javascript, jquery, etc however they all return null or 0, i can get it to work by actively setting the height however this is not very effecient and occasionally buggy, is there a way I can get the height of a dynamically created html table row/cell?

#JoseRuiSantos comment is a better implementation if your design allows it (i.e. combine data in both tables in to a single table and accordingly render rows and columns to display as two different tables using css).
One way I could think is to try using javascript:
For this to work, do not set any table/row/column heights in both tables.
Add an empty column at the end of each table with a div element in it. In the page load completed event, identify the max column height in corresponding row of both tables and set the corresponding div element's (in both tables) height (in corresponding row) to the column max height.

Javascript Fix Table Header

I am having trouble to fix the header of a table, here is my issue:
I used the same code from this post:
Table header to stay fixed at the top when user scrolls it out of view with jQuery
It is almost working, but the problem is the width of the header changed when I scroll down.
I wonder what I am doing wrong. I tried the following code to fix the width, but does not work.
$("#header-fixed td").each(function(index){
var index2 = index;
$(this).width(function(index2){
return $("#table-1 td").eq(index).width();
});
});
Here is the link:

The width of table cells is determined by not only the content of that particular table cell, but also the other cells in the same vertical column as it. This is because tables form blocks so the widths of the columns must line up.
What's happening here is that the calculated width of your attached thead cells is different from the widths calculated for your detached, fixed thead cells.
In the attached thead, the widths of the cells are largely determined by the data below. In the second instance, which isn't attached to the tbody, the width is solely determined by the header tds.
One solution would be to specify the width of the cells in both theads. As an example, specifying,
<td style='...; width: 50px;'>
on all of your thead cells would make them equal.
You could also use javascript to determine the width of each attached thead cell and set the bottom thead cells to be equal to their corresponding cell. Calculating the dimensions of DOM elements can be done with Javascript/Jquery. Check out answers like this one for methods on how to do that.

Scrollable HTML table with top row and left column frozen

Has anyone been able to implement a scrollable table in HTML where the TOP row and LEFT columns are frozen, but the rest of the table is scrollable? A perfect example of this is:
Google Squared
I tried to reverse engineer the code for the google squared table, but I have been unsuccessful so far.
Note: I need the ability to FREEZE the TOP ROW and the LEFT COLUMN at the same time.

There's a working example at http://ajaxian.com/archives/freeze-pane-functionality that should be easy to duplicate. Be sure to note the comments -- many of the users have made helpful suggestions for improving the script.
Per #Nirk's request, a direct link to the active demo is at http://www.disconova.com/open_source/files/freezepanes.htm.

Go with a basic structure like this-
table
row
column (blank)
column
table (1 row high, column headers)
row
column
table (1 column wide, row headers)
column
div (fixed height & width, overflow auto)
table (actual data)
Set a fixed table-layout and specify column widths in pixels explicitly. You should be able to achieve the same effect.

i have a version of this in use (for a Gantt-chart style display).
it uses 3 tables: 1 for left column (the rows), 1 for top (columns), and then the data.
you need to work hard to get the cells to match sizes with the ones they match up to (
table layout-fixed can help achieve this).
The tables then are placed in some divs; the left and top divs have (as suggested above) height & width and overflow-auto in their css.
You then hook up some javascript to sync the scrolling of the left / top divs with the inner one...
As I recall there was a fair bit of 'curse-and-try-again', but it can be done with minimal js.

If you use jQuery there's a lot of plugins for tables with fixed head.

You need Scrollable (jQuery plugin)

Table Row SHOW / HIDE *Without* Column Width Resizing, w/ TableLayout: auto

I have table with multiple rows, showing items for sale. When the user clicks on a row, a Javascript inserts / shows a new row right beneath it with details about the item. The issue is when the description is long, it forces the column widths to readjust / resize. This shifts the columns positions and is really annoying, especially for the user. Right now, I have my table.style.tableLayout: auto. I actually prefer it this way, because the columns are adjusted to the content.
My question is: how do I dynamically "lock" the widths of the columns in my table so that when I insert / show the new row, the columns do not readjust / resize?
I've tried:
dynamically setting the table to temporarily "tableLayout: fixed"
inserting / showing my new row
changing the table back to "tableLayout: auto"
Actions 1 & 2 works in in FireFox, but not in Safari and IE (6 & 7). However, doing all three seems to prevent the columns from shifting too much.
The frustration is unbearable ... loosing lots of sleep ... please help!
Thanks.

For those looking for the code (this is done in jQuery). This also assumes the first row has the proper widths for each cell. Pretty easy changes if needed.
$('table.class_of_table_to_fix tr:first td').each(function() {
$(this).css({'width': $(this).width()+"px"});
});

I would set a percent width on each column simply as a guide. Set it just once on the TH of each column. The browser will still adjust the columns to content if necessary, but the columns will stay in place more consistently.
Next, I would never put css "white-space:nowrap" anywhere on that table. A long description should not break the table layout, it should wrap around properly on multiple lines, and be readable if you set the widths on each column to suit the type of data. Similarly I would keep the use of (non breakable spaces) to dates, times and numbers and allow the text to wrap.
Other than that, I do this at my job on a dialy basis, and there's a time when you need to stop ulling hairs asking the browser to do something it's not designed to do. Content should flow and adapt. Locking column widths to pixels is 99.99999% of the time a bad idea.
PS: If you really, reeally, REALLY need to lock columns, the only solution I'm aware of that works with CSS2 and accross all browsers is to use images. You could insert a 1px high transparent gif image in each column, and counting in the padding of the cells (TD), set a pixel width on each image (IMG), instead of on the columns (TH/TD). You could hide those in the TH for example. You can leave the images at 1 pixel wide and set percent widths on TDs, and when you open a new row, you would get each column width minus TD Padding, and set that to the corresponding IMG. I haven't tried! I just know that in many projects I've worked on, I've used small gif images to lock a minimum vertical spacing between columns, for example.

I had a similar problem when I was implementing a table with groups that could be toggled. I wanted the initial ratio between the columns to stay the same without fixing the widths of the columns. By default the browser would change the widths depending on the visibility of the table's rows, which was undesirable.
I went ahead and followed #faB's suggestion of applying percentages, but doing so using a small script that would calculate the percentages of the th elements and apply them after the initial render. This made my columns stay the same width, even with all rows hidden.
Here's the script, which uses jQuery:
(function($){
var lock_widths = function() {
var total_width = $('table').innerWidth();
var headers = $('table th');
var leftover = 100;
$.each(headers, function(ix, el) {
var header = $(el), width;
// on the last call use the leftover percentage
if (ix == headers.length - 1) {
width = leftover;
} else {
leftover -= width = header.outerWidth() / total_width * 100;
}
header.css({'width': width + '%'});
});
};
$(document).ready(lock_widths);
})(jQuery);
Tested in IE7+, Firefox and Chrome. This works for my special case because I have header columns as a reference, but it could be rewritten to measure some other columns.

You can display the details of the row beneath the clicked one in DIV and set its
style="overflow:auto";
so that details will wrap and scrollbar will be available to display entire text.

I don´t know if you´re familiar with jquery, but that´s what I would use - in combination with a separate class for the column that´s causing resizing in the new row - to:
Calculate / get the with of the column
Set the with of the afore mentioned class
Add the row
I haven´t tried it, but that should do it.
By the way, there are probably other ways to do it, I´m just more familiar with jquery (for point 1. and 2.).
