colA     colb      concatenated

mm
         qq        qq

谢谢你的帮助

function ConCat() {
    var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Elements");
    var lr = sheet.getLastRow();
    var values1 = sheet.getRange(1, 1, lr,1).getValues();  //Get vales for Column1
    var values2 = sheet.getRange(1, 2, lr,1).getValues();  //Get values for column 2
    var results = [];                               //Create a empty array to be filled concatenated elements

    //Add items to results
    for(var i=0; i<lr; i++){
        results[i] = (values1[i][0]+", "+values2[i][0]);
    }

    //Post back to column 3 starting on row 2
    sheet.getRange(2, 3, lr, 1).setValues([results]);
}

Answer 1

setValues 想要一个二维数组。你有一个一维数组。改变

结果[i] = (值1[i][0]+","+值2[i][0]); 到

results[i] = [values1[i][0]+", "+values2[i][0]];

并改变

sheet.getRange(2, 3, lr, 1).setValues([结果]); 到

sheet.getRange(2, 3, lr, 1).setValues(results);
