要创建对角单元格，请按照以下示例操作：
您可以使用 divergeDirection 方法来获取和设置对角单元格类型的分叉方向。分叉方向的值类型是 DivergeDirection 枚举。
topLeftToButtomRight: 表示从左上到右下分叉。
bottomLeftToTopRight: 表示从左下到右上分叉。
不同的 divergeDirection 设置会创建不同的对角分叉方向。对角线的值取决于工作表中单元格的值。您可以使用 setValue 方法来设置单元格的值。如果单元格的值是字符串，则必须使用逗号（,）来分隔项目。在这种情况下，项目不能包含逗号。例如：
如果您想使用包含逗号的项目，可以将字符串数组设置为单元格的值。如果数组中的项目不是字符串，则会先将项目值转换为字符串。例如：
使用 lineBorder 方法为对角单元格设置 lineBorder。lineBorder 将改变对角线的样式。例如：
var spreadNS = GC.Spread.Sheets;
var spread, formulaBox;
window.onload = async function () {
spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
spread.suspendPaint();
initSpread(spread);
