JS changes width of tbody?

I have an table in my HTMl view (php mvc).
The table displays some basic information in a row.
By clicking the 'More' botton (+) you can see other information belonging to this user.
But somehow activating the JS chances the width of the affected row and the rows below, and slightly the first row.
How is this possible? And how can I prevent this?
Any help is welcome.
The code is in a fiddle here https://jsfiddle.net/jdkosnl/e71ms5ar/41/
$(document).ready(function () {
$('.show-more-button').click(function () {
var $this = $(this);
var forId = $(this).data('more-for');
var $showMoreElement = $(this).closest('table').children('.show-more[data-more-id="' + forId + '"]');
if ($this.hasClass('fa-plus-square')) {
$this.removeClass('fa-plus-square').addClass('fa-minus-square');
$showMoreElement.css('display', 'block');
} else if ($this.hasClass('fa-minus-square')) {
$this.removeClass('fa-minus-square').addClass('fa-plus-square');
$showMoreElement.css('display', 'none');
}
});
});

Try to avoid using display: block when working with tables and their elements. The suitable value for tbody is 'table-row-group' (instead of 'block'). Like this:
if ($this.hasClass('fa-plus-square')) {
$this.removeClass('fa-plus-square').addClass('fa-minus-square');
$showMoreElement.css('display', 'table-row-group');
}
JSFiddle.

Select hidden elements and manipulate them with jQuery

Within a div wrapper with a class of "section", I have dozens of HTML elements repeated across the page that look like this:
<div class="section">
<div class="article"></div>
<div class="article"></div>
<div class="article"></div>
</div>
And each contains certain information inside. Now, what I'm trying to do is once the page loads, show only the first 5, hide the rest in a new div inserted with jQuery, and when this new div is clicked it will display the next five , and then the next five on click again, and so on until the end. The idea is that this new div will function as a button that will always be positioned at the end of the page and will respond to these orders I just mentioned. So far I've got this down:
$('.section').each(function () {
var $this = $(this),
$allArticles = $this.find('.article');
if ($allArticles.length > 5) {
$('<div/>').addClass('hidden-articles').appendTo(this).append($allArticles.slice(5));
$('.hidden-articles .article').hide();
}
});
And that hides all but the first five. But now for the rest of the process, I can't get it to work. I don't seem to be able to select properly those hidden div with class "article" and manipulate them to function the way I described above. I would appreciate it a lot if someone more experienced with jQuery could guide me in the right direction and maybe offer a snippet. Many thanks in advance!

You can use the :hidden and :lt selectors to get the functionality you are looking for..
$('.section').each(function() {
var $this = $(this),
$allArticles = $this.find('.article');
if ($allArticles.length > 5) {
$('<div/>').addClass('hidden-articles')
.appendTo(this).append($allArticles.slice(5));
$this.find('.hidden-articles .article').hide();
}
});
$('#show').on('click',function() {
var $hidden = $('.hidden-articles .article:hidden:lt(5)');
$hidden.show();
});​
UPDATE
// If one one element to search
var elem = '.section' ;
hideArticles(elem);
// If Multiple Elements on the page...
$('.section').each(function() {
hideArticles(this);
});
$('#show').on('click', function() {
var $hidden = $('.hidden-articles .article:hidden:lt(5)');
$hidden.show();
});
function hideArticles(elem) {
var $this = $(elem),
$allArticles = $this.find('.article');
if ($allArticles.length > 5) {
$('<div/>').addClass('hidden-articles')
.appendTo(this).append($allArticles.slice(5));
$this.find('.hidden-articles .article').hide();
}
}​

What's the smartest way to select specific table elements in javascript?

I've got a table with hidden rows on it, like such
-visible-
-invisible-
-visible-
-invisible-
When I click on a table row, I want it to show the invisible row. Currently I have that using this function:
var grid = $('#BillabilityResults');
$(".tbl tr:has(td)").click(
function () {
$(grid.rows[$(this).index()+1]).toggle();
}
However, this table also hides the visible rows if I click on one of the (now visible) hidden rows.
I'd like the click function to only work on the specific visible rows. Currently all my invisible rows have the class "even" so I figured I could limit the click based on that. However, I can't seem to find the syntax to explain that to my function. How would I go about doing that? And, more importantly, is there a better way to approach this?

Use next:
$(".tbl tr:has(td)").click(
function () {
$(this).next().toggle();
}
);
And also if you have specific selector for odd or even:
$(".tbl tr.odd").click(
function () {
$(this).next().toggle();
}
);
But I think that the major help with my answer is to use next() that get you the next row, instead of the index process that you were doing.

var grid = $('#BillabilityResults');
$(".tbl tr:visible").click(
function () {
$(this).next('tr').toggle();
});

Use the NOT function to disregard the EVEN tr elements:
http://jsfiddle.net/7AHmh/
<table class="tbl">
<tr><td>one</td></tr>
<tr class="even" style="display:none"><td>two</td></tr>
<tr><td>three</td></tr>
<tr class="even" style="display:none"><td>four</td></tr>
</table>​
$(".tbl tr:has(td)").not("tr.even").click(function() {
alert("Click triggered.");
$(this).next("tr").show();
});

I guess you could check for even/odd rows with the modulus operator before calling your toggling code:
function() { // your anonymous function
if (rowNumber % 2 == 0) { // only even rows get through here
// toggle code here
}
}
I hope it helps.

Hide a table row with filtering jquery

I have the following example http://jsfiddle.net/zidski/MxqRu/1/
When you click on 2010 I need valuation to disappear with the list items.
Here is the code which I am using to do this:
$("#yearfilter a").live("click", function(e) {
e.preventDefault();
//var v = $(this).val();
var v = $(this).attr("data-value");
if(v.length > 0) {
$('tr.reports').show();
$('tr.reports ul').hide();
$('tr.reports ul.year-'+v).show();
$('tr.reports').each(function() {
if($('ul:visible', this).size() == 0) {
$(this).hide();
}
});
} else {
$('tr.reports').show();
$('tr.reports ul').show();
}
});

I have done it in my project something like this:
function toggleRow(row_id) {
row_selector = "#row_" + row_id;
$(row_selector).toggleClass("shown hidden")
}
Then in the CSS:
.hidden {display:none;}
.shown {}
Then in the HTML I have alternating table rows, where the odd rows act as headings for the content in the even rows. Clicking an odd row toggles the visibility of the corresponding even row.
...
<tr onclick="toggleRow(17)">...</tr>
<tr class="hidden" id="row_17">...</tr>
...

Give each tr an ID something like id="row_2010" then look for that and hide the whole entire row at once.
UPDATE
I would strongly suggest not using so many tables and use more classes to classify your data structure. It would help your javascript be much more clean, concise and function easier.

I adjusted all your javacsript and some of your html. Here is a fully working example jsFiddle Demo

How can I hide empty html table cells with jQuery?

I have a 5×7 HTML table. On many queries, there are fewer than 35 items filling the complete table.
How can I "hide" the empty cells dynamically in this case, using jQuery (or any other efficient way)?

Edit - Improved Version
// Grab every row in your table
$('table#yourTable tr').each(function(){
if($(this).children('td:empty').length === $(this).children('td').length){
$(this).remove(); // or $(this).hide();
}
});
Not tested but seems logically sound.
// Grab every row in your table
$('table#yourTable tr').each(function(){
var isEmpty = true;
// Process every column
$(this).children('td').each(function(){
// If data is present inside of a given column let the row know
if($.trim($(this).html()) !== '') {
isEmpty = false;
// We stop after proving that at least one column in a row has data
return false;
}
});
// If the whole row is empty remove it from the dom
if(isEmpty) $(this).remove();
});

Obviously you'll want to adjust the selector to fit your specific needs:
$('td').each(function(){
if ($(this).html() == '') {
$(this).hide();
}
});

$('td:empty').hide();

How about CSS empty-cells
table {
empty-cells: hide;
}

I'm voting for Ballsacian's answer. For some reason,
$('table#myTable tr:not(:has(td:not(:empty)))').hide();
has a bug. If you remove the outermost :not(), it does what you'd expect, but the full expression above crashes jQuery.
