是否可以使用公式设置Google电子表格单元格的背景颜色? [英] Is it possible to set the background color of a google spreadsheet cell with a formula?

问题描述

我了解条件格式，但我希望能够使用公式指定颜色.我正在设计一些颜色淡入淡出算法，并在电子表格中计算RGB值.我想将3个R，G和B值放入列中，并让第4列显示颜色.

I know about conditional formatting, but I'd like to be able to specify the color with the formula. I'm designing some color fade algorithms and am calculating the RGB values in a spreadsheet. I'd like to put my 3 R, G, and B values in columns and have the 4th column show the color.

推荐答案

不带公式，Apps脚本上的onEdit可以做到，但效率不高:

Not with formulas, an onEditon Apps Script could do that, but wouldn't be efficient:

function componentToHex(c) {
    var hex = c.toString(16);
    return hex.length == 1 ? "0" + hex : hex;
}

function rgbToHex(r, g, b) {
    return "#" + componentToHex(r) + componentToHex(g) + componentToHex(b);
}

function onEdit(){
  var RGBVals = SpreadsheetApp.getActiveSheet().getDataRange().getValues(),
      backSet = [],
      currLin;

  for( lin in RGBVals ){
    currLin = RGBVals[ lin ];
      backSet.push([rgbToHex(currLin[0], currLin[1], currLin[2])]);
  }

  SpreadsheetApp.getActiveSheet().getRange(1, 4, backSet.length).setBackgrounds(backSet);
}

注意:A，B，C列中的R，G，B，从第1行开始.

Note: R,G,B in A,B,C column, starting in ROW 1.
