根据十六进制值设置单元格的背景颜色

Question

我想根据另一个单元格中的十六进制值将背景颜色设置为一个单元格。到目前为止我所做的：

function setColorHEX(hex) {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var cell = ss.getActiveCell();
  cell.setBackground(hex);
}

有人知道我做错了什么吗？

我试图做同样的事情并找到了这个脚本。它工作得很好，尽管我确实必须突出显示所有现有的单元格并将它们复制/粘贴回去才能使其工作。信用：https ://gist.github.com/wjmazza/131c050b88bb2a595d6049707693ec13
