    I want to remove certain functions from the autocomplete when a user begins editing a cell inside a table. I still want those functions to be available on the rest of the sheet. I also want them to no be visible in autocomplete.

    Is it possible the disable and reenable functions?

    Can you place provide an example snippet.

    Hi Jeff,

    If I understand correctly you want to disable the suggestion dialogbox.For this, you may use the enableFormulaTextbox option and EditStarting Event and disable option for the particular cell. Please refer to the following code snippet and the attached sample and let us know if you face any issues.

    sheet.bind(GC.Spread.Sheets.Events.EditStarting, (e, args) => {
    if (args.col === 0) {
    spread.options.enableFormulaTextbox = false;
    } else {
    spread.options.enableFormulaTextbox = true;

    Not quite. I want to "remove certain functions" from the formulaTextbox. I do not want disable it. I only want a limited set of functions to be available [SUM, AVERAGE, CONCAT]. Can I remove functions from the autocomplete/dropdown? Can I add the functions back?

    Hi Jeff,

    Sorry for the delayed response. We are unable to achieve the required functionality using the current public API hence we have escalated this issue to our devs. We will update you regarding this as soon as get any information from the Devs. The internal ID for this issue will be SJS-6502.

    Hi Jeff,

    SpreadJS does not support this feature natively.. But you may override FormulaTexbox.add method for the required functionality. Please refer to the following code snippet and let us know if you face any issues.

    var addFn = GC.Spread.Sheets.FormulaTextBox.FormulaTextBox.prototype.add;
    GC.Spread.Sheets.FormulaTextBox.FormulaTextBox.prototype.add = function (functions) {
    var temp = [], spread = GC.Spread.Sheets.findControl("ss"), sheet = spread.getActiveSheet();
    var activeRowIndex = sheet.getActiveRowIndex(), activeColIndex = sheet.getActiveColumnIndex();
    functions.forEach(function (fn) {
    //Sum is disabled for Cell (0,0)
    if (fn.name === "SUM" && activeRowIndex === 0 && activeColIndex === 0) {
    addFn.apply(this, [temp]);
    window.onload = function () {
    var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 4 });
