如何在数组公式中使用过滤器？

Question

我有一个退出表单，我想仅使用公式找出哪些退出。

我的思考过程是找到每个标签的最后一个实例的行号，如果 "out" 行号高于 "in" 行号，则设备当前已检出。

我能够找到所有已检查过的备件：=sort(UNIQUE(C2:C))

我已经能够找到每个使用的最后一个实例的行号：=max(filter(row(C:C),C:C=F2))（我的排序唯一函数在 F 列中）。

我想让我的最后一行公式与数组公式一起使用，这样我就不必依赖手动向下拖动公式。

例如，我希望这样可以工作：=arrayformula(max(filter(row(C:C),C:C=F:F))) 注意 arrayformula 的添加以及从 F:2 到 F:F 的更改。

我不太清楚为什么，但我得到的结果是 1000。

编辑：我的预期输出是 "Last checkout row"。

Out Unique  Last checkout row
Spare1-01   6
Spare1-02   8
Spare1-03   5

如果我能弄清楚将它添加到数组公式中，我还想找到一种方法来进行排序（独特的功能，以便它成为一个单一的公式，我在列号中输入它并吐出输出每个唯一术语的最后一行编号）。

编辑（使用最终公式）（我非常感谢@JVP 的帮助）：

=ArrayFormula( if(vlookup(unique(filter(C2:C, len(C2:C))), sort({C2:C, A2:B, row(A2:A)},4,0), 4, 0) > iferror(vlookup(unique(filter(C2:C, len(C2:C))), sort({D2:D, A2:B, row(A2:A)},4,0),4,0),0), vlookup(unique(filter(C2:C, len(C2:C))), sort({C2:C, A2:C, row(A2:A)},5,0), {2,4,3}, 0), ))

Answer 1

对于您想要的输出（包括名称），请尝试：

=ArrayFormula({unique(filter(C2:C, len(C2:C))), vlookup(unique(filter(C2:C, len(C2:C))), sort({C2:C, A2:B, row(A2:A)},4,0), 4, 0)})

根据您的思考过程（最终您想查看设备当前是签入还是签出，对吗？），尝试：

=ArrayFormula({unique(filter(C2:C, len(C2:C))), if(vlookup(unique(filter(C2:C, len(C2:C))), sort({C2:C, A2:B, row(A2:A)},4,0), 4, 0) > iferror(vlookup(unique(filter(C2:C, len(C2:C))), sort({D2:D, A2:B, row(A2:A)},4,0),4,0),0), "checked out", "checked in")})

Answer 2

谢谢@JPV 这是我使用的最终公式，我改变了周围的东西，所以我所要做的就是输入列数和列数：

=sort(ArrayFormula( if(vlookup(unique(filter(INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE), len(INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE)))), sort({INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE),row('Form Responses 1'!A2:A)},2,0), 2, 0) > iferror(vlookup(unique(filter(INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE), len(INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE)))), sort({INDIRECT("'Form Responses 1'!"&"R2C5:C5", FALSE),row('Form Responses 1'!A2:A)},2,0), 2, 0),0), vlookup(unique(filter(INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE), len(INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE)))), sort({INDIRECT("'Form Responses 1'!"&"R2C4:C4", FALSE), row('Form Responses 1'!A2:A), INDIRECT("'Form Responses 1'!"&"R2C1:C"&COUNTA('Form Responses 1'!1:1)&"", FALSE)},2,0), {3,4,6}, 0), )))

我正在以编程方式创建脚本，这是代码。

function createReportSheet(setName) {
  if (!setName){setName = "Items"};
  var destId = FormApp.getActiveForm().getDestinationId();
  var as = SpreadsheetApp.openById(destId);
  try{
  var sheet = as.insertSheet("Report Out: "+setName);
  } catch(err){
   var sheet = as.getSheetByName("Report Out: "+setName);
   sheet.clear(); 
  }  


  //build formula
  var formSheetName = "'Form Responses 1'!";
  var colOut = 4;
  var colIn = 5;
  var colToShow = "3,4,6"; //  A=3, B=4, C=5, .. 

  var frTimeStamp = formSheetName+"A2:A";
  var lastCol = "&COUNTA("+formSheetName+"1:1)&";

  var frSort = 'INDIRECT("'+formSheetName+'"&"R2C'+1+':C"'+lastCol+'"", FALSE)';
  var frIn  = 'INDIRECT("'+formSheetName+'"&"R2C'+colIn+':C'+colIn+'", FALSE)';
  var frOut = 'INDIRECT("'+formSheetName+'"&"R2C'+colOut+':C'+colOut+'", FALSE)';

  //break into parts
  var f_unique = "unique(filter("+frOut+", len("+frOut+")))";
  var f_sortIn = "sort({"+frOut+",row("+frTimeStamp+")},"+2+",0)";
  var f_vlookupIn = "vlookup("+f_unique+", "+f_sortIn+", "+2+", 0)";
  var f_sortOut = "sort({"+frIn+",row("+frTimeStamp+")},"+2+",0)";
  var f_vlookupOut = "vlookup("+f_unique+", "+f_sortOut+", "+2+", 0)"; 
  var f_sortDisp = "sort({"+frOut+", row("+frTimeStamp+"), "+frSort+"},"+2+",0)";
  var f_vlookupDisp = "vlookup("+f_unique+", "+f_sortDisp+", {"+colToShow+"}, 0)"; 
  var formula1 = "ArrayFormula( if("+f_vlookupIn+" > iferror("+f_vlookupOut+",0), "+f_vlookupDisp+", ))";
  var formula = "=sort("+formula1+")";

  // put formula into sheet
  sheet.getRange(2, 1).setFormula(formula);
  sheet.getRange("a:a").setNumberFormat("mm/dd/yy h:mm:s");

}
