如果你在公式中输入一个区域，区域指示器也会显示出来。你可以使用鼠标来选择一个区域。
你可以使用Function类来添加自定义的函数。例如：
你还可以获取自定义函数的描述：
您可以通过修改 CSS 定义来更改跨工作表的单元格公式文本框及其弹出元素：
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;
var fbx = new spreadNS.FormulaTextBox.FormulaTextBox(document.getElementById('formulaBar'));
fbx.workbook(spread);
spread.suspendPaint();
var sheet2 = spread.sheets[1];
sheet2.setArray(0, 0, [[1, 4, 7], [2, 5, 8], [3, 6, 9]]);
var sheet = spread.sheets[0];
sheet.options.allowCellOverflow = true;
sheet.setValue(1, 2, "A helpful text box is displayed when typing any formula in a cell or the area above the sheet.");
sheet.setValue(2, 2, "For example: =sum(1,2,3)");
for (var i = 5; i < 35; i++) {
for (var j = 1; j < 15; j++) {
sheet.setValue(i, j, i * j);
}
}
// used to help show table support feature
sheet.tables.add("Table1", 4, 7, 5, 4);
for (var c = 7; c <= 10; c++) {
sheet.setColumnWidth(c, 90);
}
sheet.setFormula(3, 0, "Table1[[#Headers],[Column2]]");
// used to help show custom name support feature
sheet.addCustomName("RangeB6C9", "$B$6:$C$9", 0, 0);
sheet.addCustomName("Range2", "SUM($C$11:$D$14)", 0, 0);
sheet.setFormula(4, 0, "AVERAGE(RangeB6C9)");
// used to help show multi supported reference types
var formula = "SUM(B6:C9,E6:F9,Table1[#Data],Range2,F11:J14,D16:I17)";
sheet.setActiveCell(1, 0);
sheet.getCell(1, 0).formula(formula);
fbx.text("=" + formula);
// used to help show cross sheet reference
sheet.setFormula(5, 0, "SUM(sheet2!A1:C3)");
sheet.getRange(1, 0, 5, 1).foreColor("green");
spread.resumePaint();
