How to remain scroll at the right end after removing the last column on flat table

Hello, Tigran!
 
Kindly note that by design, Flexmonster scrolls to the far left end of the grid every time the field is removed. This behavior can be overridden by using Flexmonster beforegriddraw, aftergriddraw, reportcomplete and reportchange events along with scrollTo() API call as follows:

let handler = () => {
    scrollPane = document.querySelector("#fm-pivot-view div.fm-data-sheet > div.fm-scroll-pane")
    x = scrollPane.scrollLeft;
    y = scrollPane.scrollTop;
};

pivot.on("reportcomplete", () => {
    pivot.on("beforegriddraw", handler)

    pivot.on('reportchange', () => {
      pivot.off('reportchange');
      pivot.off('beforegriddraw', handler);

      pivot.on('aftergriddraw', () => {
        pivot.off('aftergriddraw');

        setTimeout(() => {
          scrollPane.scrollTo(x, y);
        }, 0);

      });
    })
});

We have prepared the JSFiddle example for reference: https://jsfiddle.net/flexmonster/r5b4eq2L/.

Hello, Tigran!

Hope you are doing well.

Hello, Tigran!
 
Thank you for getting back to us.
 
Kindly note that the suggested approach can't control the scroll with 100% accuracy as we don't save and restore the pixels, only the scroll position. 
It is possible to adjust the approach more by catching the last column removed and scrolling to the far right end in this case. For that, you need to compare the fields in the report before and after the reportchange. The fields can be retrieved by using the getReport() API call.
 
Hope it helps.
