想要设置单元格类型，首先就要创建一个单元格类型对象，然后使用 setCellType 方法将单元格类型设置到表单，单元格，列，行上。例如：
你可以通过将单元格类型绑定到列上这种方式来使用单元格类型。比如：
当你设置完单元格类型后，可以使用 getCellType 方法获取单元格类型。如果你想移除单元格类型，你可以将单元格类型的值设置为 null 或者 undefined。
SpreadJS 在 Spread 上提供了一个事件 (ButtonClicked) 。如果你点击了按钮，复选框或者超链接事件就会触发。例如：
window.onload = function() {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 2 });
initSpread(spread);
};
function initSpread(spread) {
var spreadNS = GC.Spread.Sheets,
sheet = spread.getSheet(0);
var eventTrigger = document.getElementById("eventTrigger");
spread.bind(spreadNS.Events.ButtonClicked, function(e, args) {
var text = "";
if (eventTrigger.value === "undefined") {
eventTrigger.value = "";
}
var sheet = args.sheet, row = args.row, col = args.col;
var cellType = sheet.getCellType(row, col);
if (cellType instanceof GC.Spread.Sheets.CellTypes.Button) {
text = eventTrigger.value + "You click a button.\n";
}
if (cellType instanceof GC.Spread.Sheets.CellTypes.CheckBox) {
text = eventTrigger.value + "You click a check box.\n";
}
if (cellType instanceof GC.Spread.Sheets.CellTypes.HyperLink) {
text = eventTrigger.value + "You click a hyperlink.\n";
}
eventTrigger.value = text;
});
spread.bind(spreadNS.Events.CellClick, function(e, args) {
var text = "";
if (eventTrigger.value === "undefined") {
eventTrigger.value = "";
}
var sheet = args.sheet, row = args.row, col = args.col;
var cellType = sheet.getCellType(row, col);
if (cellType instanceof GC.Spread.Sheets.CellTypes.ComboBox) {
text = eventTrigger.value + "You click a combo box.\n";
}
eventTrigger.value = text;
});
sheet.suspendPaint();

sheet.setValue(4, 1, "HyperLinkCellType");
sheet.resumePaint();
