Question

我有一张表，比如说它叫raw sheet：

Column Index | A | B  |
David        | 1 | 10 |
Jerry        | 5 | 15 |
David        | 1 | 50 |
Jerry        | 6 | 20 |
David        | 8 | 20 |

列索引中只有有限的值。就像在这种情况下只有“大卫”和“杰里”。

我想创建另一个工作表，比如称为summary sheet，它可以按列索引值汇总一些值，如下所示：

Column Index Summary | f(A,B)     |
David                | some value |
Jerry                | some value |

f（A，B）可以是任何一种利用第一张纸中所有值的函数。一个例子：添加每一行的A * B以获得一个新数字。在这种情况下，它将是：

Column Index Summary | f(A,B)     |
David                | 220        | that is 1*10 + 1*50 + 8*20
Jerry                | 195        | that is 5*15 + 6*20

我该怎么办？

Answer 1

这是适用于您的Google表格自定义功能。它将在任意数值数据表上运行，通过任意（但简单）的代数表达式聚合数字。（表达式必须在Javascript中有效，例如"A * B"，"A + B / C"，甚至"Math.pow(A,B)"。）没有错误检查，所以它不是万无一失的。

示例：

=summary('raw sheet'!A1:C6,"A*B")是的，你可以参考不同的表格。

=summary(A1:C6,"A*A + B")

=summary(A1:C6,"Math.pow(A,B)")

function summary(table,formula,sortType,sortColumn) {
  sortType = (sortType == undefined) ? 1 : sortType;
  sortColumn = (sortColumn == undefined) ? 1 : sortColumn;

  // Sort comparison function for ordering summary table
  // uses sortType & sortColumn
  function colCompare(a,b) 
  {
    var col = sortColumn - 1;
    var order = sortType;
    if (!order) return 1;
    else 
    return ((a[col] < b[col]) ? -order : ((a[col] > b[col]) ? order : 0));
  }

  var headers = table[0];

  // Start results with its header row
  var summaryTable = [[headers[0],String(formula)]];

  // evaluate formula, replacing variables (headers) with references to table
  for (var h = 1; h < headers.length; h++) {
    var re = new RegExp(headers[h],"g");
    formula = formula.replace( re, " table[row]["+parseInt(h)+"] " );
  }

  // Aggregate data by summing formula for each row
  var summary = {};
  for (var row=1; row<table.length; row++) {
    var key = table[row][0];
    if (!(key in summary))
      summary[key] = 0;
    summary[key] += eval( formula );
  }

  // Append aggregated rows to results, and return
  for (key in summary) {
    summaryTable.push([key,summary[key]]);
  }

  // Sort the results
  headers = summaryTable.splice(0, 1);
  summaryTable.sort(colCompare).unshift(headers[0]);
  return summaryTable;

Answer 2

假设您在Col A中有名称，并且该示例的col A实际上是Col B，在摘要表中，尝试类似：

=ArrayFormula(query({'raw sheet'!A2:A,'raw sheet'!B2:B*'raw sheet'!C2:C}, "select Col1, sum(Col2) where Col1 <>'' group By Col1 label sum(Col2) 'TOTAL' "))
