I´ve seen some people around the web wondering about a code to reorder table columns using the mouse (drag and drop). Since i had already made one script to reorder table lines (TR´s) i decided to start working in one to reorder the columns. Im sharing this code with you all now. If anyone find any issue needing improvements just email-me and i will try to fix. The implementation is very easy, only change the ID of the table in the tabelaDrag variable and it should work.
ps:english is not my primary language so... :)

/* estilo geral da tabela */

table {border-collapse:collapse}

table td {border:1px solid #000; padding:2px 5px; text-align:center; cursor:pointer}

/* classe das cores utilizadas na movimentação */
-
.hover {background:lightblue}

.selecionado {background:lightgreen}

Tested for macintosh:
Works in Firefox 1.5.0.6 for mac.
Works in Opera 9.01 for mac.
Does not work in Safari 2.0.4.
It's pretty nice, and simple. I might take a crack at debugging Safari and posting the results.
Great code.
But can you enhance it so that when a column is dragged(the selected column), it is visible when you hover over a different column.
Great code.
But can you enhance it so that when a column is dragged(the selected column), it is visible when you hover over a different column.
The code is actually just using some css to change colors. The selected column becomes green while the mouse is pressed and the place where it will drop is blue.
I think you are talking about making the whole column to be "floating" with the mouse cursor. To do that we need a function to get the mouse coords and make the element that we click and drag to use position:absolute and to follow these coords. The functionality will be the same in end.
An example of that function to move the elements: Drag & Drop Example
ps: im supposing i can post that link here, sorry if i don´t!
The problem is that Safari does not (correctly) implement td.cellIndex. It always returns zero. Lame.
Change all foo.cellIndex to cellIndex(foo) and add these two methods: - function cellIndex(td) {
-
var ci = -1;
-
var parent_row = ascendDOM(td, 'tr');
-
for (var i = 0; i < parent_row.cells.length; i++) {
-
if (td === parent_row.cells[i]) {
-
ci = i;
-
}
-
}
-
return ci;
-
}
-
-
function ascendDOM(e,target) {
-
while (e.nodeName.toLowerCase() !=target &&
-
e.nodeName.toLowerCase() !='html')
-
e=e.parentNode;
-
return (e.nodeName.toLowerCase() == 'html')? null : e;
-
}
Here is a custom version, which highlight selected column to move, show insertion point as a vertical line (left cells border style update) during column drag (like firefox tab drag&drop) and keep original table styles. Seems to work on my stuff, hope it will help ;) -

I forgot to write that you need to call following function to activate DD on table, example :
setTableColMovable("my_table_id","one_html_field",[0,1,2,3]);
this call initiate table DD and also specify an HTML field (hidden by example) to store reordered columns numbers list. So initial column numbers are to be passed into last param (here [0,1,2,3]) in setTableColMovable call
hope it's clear cause it is time to launch ;)
Hello again folks!
I´ve received some emails about issues on the performance of the table (especially in ie) while working with big tables (30+ columns / 100+ lines) and i´ve worked a bit more into the script to improve it!
In the older version i was using classnames to give a visual effect of the column that is being moved and to where it was being moved, having to use some loops to change all classes and then change em back to the original afterwards! All those loops were causing an annoying delay!
There are still some changes to be done like: allowing more than 1 table in the same page to have the "drag & drop" implemented! I will work on that soon!
Email me with suggestions / issues so i can improve the script
I´ve tested it only under ie/firefox/mozilla/netscape, so some feedback from other browsers are welcome
call the script using:
allowDragging(tableId)
file: movecolumn.js
file: movecolumns.css -
/* table general style */
-
table {border-collapse:collapse}
-
table td {border:1px solid #000; padding:2px 5px; text-align:center; cursor:pointer; font:bold 12px verdana;}
-
table thead td {background:#1864E0; color:#fff;}
-
-
/* drag td style */
-
-
#drag {position:absolute; border:1px solid #000; text-align:center; cursor:pointer; font:bold 12px verdana; color:#fff;}

#drag thead td {background:#1864E0; color:#fff;}

It should be noted that there are problems with the html shown above.
1) The doctype is incomplete and will throw IE into 'quirks mode' making it not behave like modern browsers. The correct doctype is discussed under the html Howto and this is the correct one to use: - <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
-
"http://www.w3.org/TR/html4/strict.dtd">
2) The <link> ends with a XHTML closing tag: /> . Since XHTML is not declared in the doctype, this may cause browsers to ignore some of the markup after it. (Perhaps causing the Safari problem?)
In any case, both of the items cause the page to be invalid.
