Custom column headers applied on dataSource are not reactive on add/remove cols

    Good morning/afternoon

    Following up this post:

    The code generates the letter references for every column, however if the user does edit the columns the column names aren't updating accordingly.


    The user creates a new column between column C and D, the new generated column has name C but the next column keeps the letter C (this applies even for delete event)

    Hi Davide,

    In this case, you may handle the ColumnChanged event and update the headers when required. Please refer to the following code snippet and the sample which demonstrates the same:

    sheet.bind(GC.Spread.Sheets.Events.ColumnChanged, function(e, args) {
    if (
    args.propertyName === "addColumns" ||
    args.propertyName === "deleteColumns"
    ) {
