Hide Columns In A Table?

Jun 28, 2011

I want to hide columns with all green cells and I stored the column # that I want to hide into an array, errorColumn(). I am able to hide the rows I want, but I can't seem to figure out the columns.

I think the .has function is the problem because when I use the if(j!=5), it'll hide all columns but the 5th one. I just need it to do that for every column in my array...

Sticky Table Columns

May 2, 2007

I have a requirement to build a div in a page that contains a table of
plane details, and one of the columns (on the left - tail number)
needs to be sticky on the horizontal axis but not on the vertical axis
(i.e. when scrolling right the tail numbers need to stay visible on
the left hand side, but when scrolling down the tail numbers need to
scroll to keep up with the rest of the plane details).

I have been looking at various ways of doing this but currently to no
avail, the idea that looks most promising is to split it into two
tables and set them both to have scroll bars, the problem with this
idea was that both the tables need to be scrolled by the same amount
vertically, i could get the position of one table using the offsetTop
property but could not find a way of setting the offsetTop property
for the other table so they stay aligned. The other issue with this is
that it would be using the onscroll property which does not seem to
show any distinction between horizontal and vertical scrolls..

Hide Columns In Tables Based On Variables?

May 28, 2010

I have a table with 1 row and 5 columns. I want to hide each column based on specific variables in the web page. Is there a way to do that. I tried a <div> tag and the below code, but it says you cannot put a <div> tag in a table etc.

Code:
document.getElementById('hiddenYearLeft').style.display = "none";
document.getElementById('hiddenYearLefta').style.display = "none";

Sorting Columns In A Table Or Form

Jul 20, 2005

I need to be able to create a 2 column table and then based on which column
header is clicked on, sort the list by that column so that each table row is
sorted properly. If possible there might be more than one line in the row
and I would only want to sort on the first line in a given row. Can this be
done using JavaScript. If so, which entities do I need (A table? A form?)

JQuery :: How To Resize Table Columns

Oct 6, 2009

I'm looking for some super light-weight technique to take an existing table and just be able to resize the column headers. I've seen several jquery table plugins out there that seem to do everything imaginable, but I don't really need any of the fancy bells and whistles. I want to use my existing table structure and styles.

JQuery :: Bind Specific Columns Of A Table Row?

Nov 17, 2010

How to I bind a click function to specific columns of a table row?

Btw, this is a (yet not answered) crosspost of [URL]

I currently have this piece of code:

$('#example tr').click( function() {
// selection stuff here, $(this) is the row
});

However, this binds the whole row. As there are checkboxes in the row, I don't want to have the cells containing them bound, too. But, there is a problem: I need to know what row has been clicked on / to what row the cell belongs to. I simply don't get it to work, I tried something like this:

$('#example tbody tr td:lt(7)').live('click', function() {
var nRow = $(this).parent();
});

JQuery :: Making Sure There Are Always 4 Columns To The Main Table?

Jun 2, 2011

I've got a website that displays all my products together within a table and the user can then click on the product they want to buy or obtain more info on. This is always displayed in four columns.

However if you have a few pages of products for one category it can be displayed across a few pages. For some reason the content management system I use will display only 1, 2 or columns on the last page if there are less than 4 products on the last page. When this happens you can get the produts displayed with a different width to what I've set within the CSS because the table's with is set to 100%.

When this happens is it possible to set the the width of the table to:

75% if there are 3 columns

50% if there are 2 columns

25% if there is only one column

Or is it possible to keep the width of the table at 100% and just add the extra columns if there are not 4?

The table id="catprods_tbl" and the columns (td) are is set to id="column_main"

I have included the example of the layout when there are only two columns on the last page.

Hiding Table Columns Is Not Working Properly?

May 29, 2010

The code works great to hide the columns. The only issue is when you un-hide them again, it does come up correctly. I want the headings to all be on the top row and then the actual data be on the next row. If you do all of them, it stacks all the headings on top of each other and then puts the data rows in order with 8 rows etc. Code is below.

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

Switch Table Rows/columns With DOM (firefox Issues)

Nov 17, 2005

I want to switch entire rows/columns around in a table. Move rows up/down and move columns left/right. This works fine in IE/opera but has a few problems in firefox.

First of all, is this the 'right' way to do this or is there a better way? Firefox doesn't support swapNode().

When moving rows up/down (top one in demo) firefox takes a few clicks to work when it should be one click on the button. I have no idea why. Code:

AJAX :: Table Columns Not Sorted By Tablekit After Call Is Added

Mar 4, 2010

I use the Tablekit library and Prototype javascript framework on firefox, chrome & IE8. The columns in this table can be sorted by the Tablekit library.

<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/tablekit.js"></script>
<body>
<div id="mainmenu">
...
</div>
<div id="content">

However, after adding the periodic refresh by AJAX (eventually I want to refresh only the web page when there is new data available) and <div>, then the columns in this table cannot be sorted by the Tablekit library.

Editable Table - With Editable Rows And Columns That Will Feed Back Into A Database

Aug 12, 2009

I'm trying to implement is a table with editable rows and columns that will feed back into a database. If I could do it with AJAX that would be great too, but I'm not too familiar with javascript. I don't need the code, I need more of an idea. The HTML Table is currently a recreation of the MySQL table minus a few columns. Its all in text, but if I could make the text editable, or better yet, make the text turn into input boxes it would be really cool. I'm not really sure what kind of methods and properties I would need, or quite how to put it all together. What do you think is the best way to go about the entire project?

Show/hide A Table Row

Jul 23, 2005

I would like to add some javascript to show/hide a certain row of a
table. The first row of the table contain the hyperlink that calls the
javascript the second row is the one i want to show/hide with the
javascript in a toggle fashion.

the problem is a know very little javascript and have become incredibly
frustrated because i went ahead thinking it was going to be like C. its not.

I know i can use these lines to do the actual work:

document.getElementById("row").style.display = "none"; // hides row
document.getElementById("row").style.display = "inline"; // shows row

but I don't think i can use a getElementById exactly because i want to
reference the element via its relationship to the hyperlink that calls
the javascript, i know this can be done. You see there will be several
tables on one page and i want to be able to toggle each one
independently; hopefully with the same bit of javascript.

Hide A Table Column In IE

May 8, 2006

I'm having a spot of bother hiding table columns in IE.

With FF, setting the column cell's style.display to none (or changing
the cell's class name to style that has display: none) completely
removes the cells from the table.

In IE, the cell contents go, but the space they occupied is still there,
so the table has an empty column, the same result as setting visibility
= invisible.
