你可以通过继承 Base 类型来自定制单元格类型，并且实现一些必须的方法，例如 paint ， createEditorElement ， getEditorValue 等等。完成了这些你就可以使用你的自定制单元格类型了。例如：
var spreadNS = GC.Spread.Sheets;
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
//Custom Cell Type
function FivePointedStarCellType() {
this.size = 10;
}
FivePointedStarCellType.prototype = new spreadNS.CellTypes.Base();
FivePointedStarCellType.prototype.paint = function (ctx, value, x, y, w, h, style, context) {
if (!ctx) {
return;
}
ctx.save();
// draw inside the cell's boundary
ctx.rect(x, y, w, h);
ctx.clip();
ctx.beginPath();
if (value) {
ctx.fillStyle = "orange";
} else {
ctx.fillStyle = "gray";
}
var size = this.size;
var dx = x + w / 2;
var dy = y + h / 2;
ctx.beginPath();
var dig = Math.PI / 5 * 4;
ctx.moveTo(dx + Math.sin(0 * dig) * size, dy + Math.cos(0 * dig) * size);
for (var i = 1; 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 };
