Custom Cell

SpreadJS provides the support for creating your custom cell type. It can be implemented using the Base class.


You can draw when the cell is in display mode, customize the editor when the cell is in editing mode, and handle mouse and keyboard interaction by the cell type itself. There are many different properties and functions that you can overwrite to get specific cells to fit your requirements.

Usage Scenario

A user wants to create interactive cells that can keep a track of whether their favorite basketball players have achieved the five-pointers in a season.


The first column contains a star shape representing the five-pointer which can toggle between lighting on and lighting off by mouse-click and depending on the boolean value.


The second column contains the names of the players, and each cell can be edited to insert the first name and the last name.


SpreadJS custom cell usage scenario


The following code sample creates two custom ranges of cells in columns A and B respectively.

window.onload = function () {

    // Configure Workbook and Worksheet
    var spread = new GC.Spread.Sheets.Workbook("ss");
    var sheet = spread.getActiveSheet();
    sheet.suspendPaint();

    sheet.getRange("A1:A5", GC.Spread.Sheets.SheetArea.viewport).cellType(new FivePointedStarCellType());
    sheet.getRange("A1:A5", GC.Spread.Sheets.SheetArea.viewport).value(false);

    sheet.getRange("B1:B5", GC.Spread.Sheets.SheetArea.viewport).cellType(new FullNameCellType());

    sheet.setValue(0, 1, { firstName: "Lebron", lastName: "James" });
    sheet.setValue(1, 1, { firstName: "Kevin", lastName: "Durant" });
    sheet.setValue(2, 1, { firstName: "Stephen", lastName: "Curry" });
    sheet.setValue(3, 1, { firstName: "James", lastName: "Harden" });
    sheet.setValue(4, 1, { firstName: "Joel", lastName: "Embiid" });

    sheet.setColumnWidth(0, 100);
    sheet.setColumnWidth(1, 180);
    sheet.setRowHeight(0, 100);
    sheet.setRowHeight(1, 100);
    sheet.setRowHeight(2, 100);
    sheet.setRowHeight(3, 100);
    sheet.setRowHeight(4, 100);
    sheet.resumePaint();
}

function FivePointedStarCellType() {
    this.fillStyle = "orange";
    this.size = 10;
}

    }
    ctx.save();
    // draw inside the cell's boundary
    ctx.rect(x, y, w, h);
    ctx.clip();
    ctx.beginPath();
    if (value) {
        ctx.fillStyle = this.fillStyle;
    } else {
        ctx.fillStyle = "gray";
    }
    var size = this.size;
    var dx = x + w / 2;

    var dig = Math.PI / 5 * 4;
    for (var i = 0; i < 5; i++) {
        ctx.lineTo(dx + Math.sin(i * dig) * size, dy + Math.cos(i * dig) * size);
    }
    ctx.closePath();
    ctx.fill();
    ctx.restore();
};

FivePointedStarCellType.prototype.getHitInfo = function (x, y, cellStyle, cellRect, context) {
    var xm = cellRect.x + cellRect.width / 2,
        ym = cellRect.y + cellRect.height / 2,
        size = 10;
    var info = { x: x, y: y, row: context.row, col: context.col, cellRect: cellRect, sheetArea: context.sheetArea };
    if (xm - size <= x && x <= xm + size && ym - size <= y && y <= ym + size) {
        info.isReservedLocation = true;
    }
    return info;
};

FivePointedStarCellType.prototype.processMouseUp = function (hitInfo) {
