ColReorder exclude right-most column

Does anyone have an implementation of this? The right-most column of my table is a Manage column with buttons in the fields and I don't want it to be Column-reorderable. Thanks for any help!

Okay, I just implemented it myself.

Changes to the colReorder.js code:

Added (to the namespace settings object):
[code]
/**
* Number of columns to fix (not allow to be reordered)
* @property fixedrtl
* @type int
* @default 0
*/
"fixedrtl": 0,
[/code]

Added (to _fnConstruct):
[code]
/* Columns discounted from reordering - counting right to left */
if ( typeof this.s.init.iFixedColumnsRtl != 'undefined' )
{
this.s.fixedrtl = this.s.init.iFixedColumnsRtl;
}
[/code]

Changed this function (find the comment):
[code]
/* Add event handlers for the drag and drop, and also mark the original column order */
for ( i=0, iLen=this.s.dt.aoColumns.length ; i this.s.fixed-1 && i < (this.s.dt.aoColumns.length - this.s.fixedrtl) )
{
this._fnMouseListener( i, this.s.dt.aoColumns[i].nTh );
}

/* Mark the original column order for later reference */
this.s.dt.aoColumns[i]._ColReorder_iOrigCol = i;
}
[/code]

Added (to _fnMouseDown):
[code]
/* Disallow columns for being reordered by drag and drop, counting right to left */
if (this.s.fixedrtl !== 0) {
this.s.aoTargets.splice(this.s.dt.aoColumns.length - this.s.fixed - this.s.fixedrtl + 1, this.s.fixedrtl);
}
[/code]

I'd recommend adding this to the code base, Allen. I've seen requests for it before and I think it'd make the colReorder extra just a bit more versatile. :-)

EDIT: Found and squashed a bug concerning fixing both left and right columns. Looks like it works great now.
