问如何从Excel Javascript外接程序检测区域中的合并单元格？

EN

    //get selected range and did merge
var range = context.workbook.getSelectedRange();
range.merge();
await context.sync();

    // check whether the range is merged or not 
range.load();
await context.sync();
console.log(range["cellCount"]);

const str = range.address;
const colCount = range.columnCount;
const rowCount = range.rowCount;
console.log(colCount);
console.log(rowCount);
if (str) {
  const arr = str.split("!");
  console.log(arr[1]);
  if ((range["cellCount"] > 1 || range["colCount"] > 1 || range["rowCount"] > 1) && arr[1].indexOf(":") == -1) {
    console.log("true");
  } else {
    console.log("false");
  }
}
