------------------------------------

Hi Lukáš,
I just tested latest 4.2.1-SNAPSHOT Version (could not find CR1 yet) and have several issues in my setup:
1. when the table is initially already exceeding the configured size vertical scrolling seems to be broken (scroller is present (diabled) with full size) 
2. for quite a lot of my tables I have issues with column-width adjustment which is just not possible - a few tables work. -> I See the mouseover but "ondrag" it just marks the column text.
3. in one usecase when initializing a table onclick on another table row by ajax update the new tabler has no scrolling bars at all.


I tested on my version also, unfortunately i reformatted the js-code so a can't post a diff but here are the canges:
1. add new Function
{code}
        adjustScrollingIssues: function() {
            var headerElem = document.getElementById(this.id + ":header");
            var bodyElem = document.getElementById(this.id + ":body");

            //compute correct width by gettong from parent div
            var parentWidth = this.scrollElement.parentNode.parentNode.parentNode.parentNode.parentNode.offsetWidth;

            this.scrollElement.style.width = parentWidth + "px";
            headerElem.style.width = parentWidth + "px";
            if (bodyElem != null) {
                //might be null in case of empty body...
                bodyElem.style.width = parentWidth + "px";
            }
           
        },
{code}
2. initialize function just before ende
{code}
            this.updateLayout();
            //>>>Begin insert

            this.adjustScrollingIssues();

            this.updateLayout();
            //this.adjustResizers();

            //<<<end insert
            this.updateScrollPosition(); //TODO Restore horizontal scroll position
{code}

still a little bit hacked but really seem to be stable now for my usecases.
