我的目标是找到一组范围的所有排列。
我遇到以下代码问题（来自：Script to permute columns, rows or any ranges）。我在单元格E1中使用了以下函数，但无济于事：
=permuteRanges(["A1:A", "B1:B", "C1:C"],[1, 2, 0],"D1:D",SpreadsheetApp.getActiveSheet())
示例：
a1,b1,c1
a2,b2,c2
期望的输出：
a1,b1,c1
a1,b1,c2
a1,b2,c1
a1,b2,c2
a2,b1,c1
a2,b1,c2
a2,b2,c1
a2,b2,c2
我希望能够更改a，b，c列，以便函数可以执行b，a，c或c，a，b。注意我需要能够更改我明确需要上面使用的b，a，c或c，a，b的列。
错误是#ERROR公式解析错误。可能是公式格式是问题吗？
// Parameters:
// - ranges An Array with ranges which contents are to be permuted.
// All the ranges must have the same size. They do not have to be
// vectors (rows or columns) and can be of any size. They may come from
// different sheets.
// Every element of the array must be either a Range object or a string
// naming the range in A1 notation (with or without sheet name).
// - permutation An Array with 0-based indexes determining desired permutation
// of the ranges. i-th element of this array says to which range
// should the contents of i-th range be moved.
// - temp A range of the same size as the ranges in "ranges". It is used to
// temporarily store some ranges while permuting them. Thus the initial
// contents of this range will be overwritten and its contents on exit is
// unspecified. Yet if there is nothing to be moved ("ranges" has less
// than 2 elements or all ranges are already on their proper places) this
// range will not be used at all.
// It is advised to make this range hidden so the "garbage" doesn't
// bother user.
// This can be either a Range object or a string naming the range in A1
// notation (with or without sheet name) - just as with the "ranges".
// - sheet An optional Sheet object used to resolve range names without sheet
// name. If none is provided active sheet is used. Note however that it
// may cause issues if user changes the active sheet while the script is
// running. Thus if you specify ranges by name without sheet names you
// should provide this argument.
//
// Return Value:
// None.
//
// This function aims at minimizing moves of the ranges. It does at most n+m
// moves where n is the number of permuted ranges while m is the number of
// cycles within the permutation. For n > 0 m is at least 1 and at most n. Yet
// trivial 1-element cycles are handled without any moving (as there is nothing
// to be moved) so m is at most floor(n/2).
//
// For example to shift columns A, B and C by 1 in a cycle (with a temp in
// column D) do following:
//
// permuteRanges(
// ["A1:A", "B1:B", "C1:C"],
// [1, 2, 0],
// "D1:D",
// SpreadsheetApp.getActiveSheet()
// );
function permuteRanges(ranges, permutation, temp, sheet) {
// indexes[i] says which range (index of ranges element) should be moved to
// i-th position.
var indexes = new Array(permutation.length);
for(var i = 0; i < permutation.length; ++i)
indexes[permutation[i]] = i;
// Generating the above array is linear in time and requires creation of a
// separate array.
// Yet this allows us to save on moving ranges by moving most of them to their
// final location with only one operation. (We need only one additional move
// to a temporary location per each non-trivial cycle.)
// Range extraction infrastructure.
// This is used to store reference sheet once it will be needed (if it will be
// needed). The reference sheet is used to resolve ranges provided by string
// rather than by Range object.
var realSheet;
// This is used to store Range objects extracted from "ranges" on
// corresponding indexes. It is also used to store Range object corresponding
// to "temp" (on string index named "temp").
var realRanges;
// Auxiliary function which for given index obtains a Range object
// corresponding to ranges[index] (or to temp if index is "temp").
// This allows us to be more flexible with what can be provided as a range. So
// we accept both direct Range objects and strings which are interpreted as
// range names in A1 notation (for the Sheet.getRange function).
function getRealRange(index) {
// If realRanges wasn't yet created (this must be the first call to this
// function then) create it.
if(!realRanges) {
realRanges = new Array(ranges.length);
}
// If we haven't yet obtained the Range do it now.
if(!realRanges[index]) {
var range;
// Obtain provided range depending on whether index is "temp" or an index.
var providedRange;
if(index === "temp") {
providedRange = temp;
} else {
providedRange = ranges[index];
}
// If corresponding "ranges" element is a string we have to obtain the
// range from a Sheet...
if(typeof providedRange === "string") {
// ...so we have to first get the Sheet itself...
if(!realSheet) {
// ...if none was provided by the caller get currently active one. Yet
// note that we do this only once.
if(!sheet) {
realSheet = SpreadsheetApp.getActiveSheet();
} else {
realSheet = sheet;
}
}
range = realSheet.getRange(providedRange);
} else {
// But if the corresponding "ranges" element is not a string then assume
// it is a Range object and use it directly.
range = providedRange;
}
// Store the Range for future use. Each range is used twice (first as a
// source and then as a target) except the temp range which is used twice
// per cycle.
realRanges[index] = range;
}
// We already have the expected Range so just return it.
return realRanges[index];
}
// Now finally move the ranges.
for(var i = 0; i < ranges.length; ++i) {
// If the range is already on its place (because it was from the start or we
// already moved it in some previous cycle) then don't do anything.
// Checking this should save us a lot trouble since after all we are moving
// ranges in a spreadsheet, not just swapping integers.
if(indexes[i] == i) {
continue;
}
// Now we will deal with (non-trivial) cycle of which the first element is
// i-th. We will move the i-th range to temp. Then we will move the range
// which must go on the (now empty) i-th position. And iterate the process
// until we reach end of the cycle by getting to position on which the i-th
// range (now in temp) should be moved.
// Each time we move a range we mark it in indexes (by writing n on n-th
// index) so that if the outer for loop reaches that index it will not do
// anything more with it.
getRealRange(i).moveTo(getRealRange("temp"));
var j = i;
while(indexes[j] != i) {
getRealRange(indexes[j]).moveTo(getRealRange(j));
// Swap index[j] and j itself.
var old = indexes[j];
indexes[j] = j;
j = old;
}
getRealRange("temp").moveTo(getRealRange(j));
// No need to swap since j will not be used anymore. Just write to indexes.
indexes[j] = j;
}
}

我使用了单元格E1中的示例中使用的以下函数但是 无济于事：
SSucc
上述问题是=permuteRanges(["A1:A", "B1:B", "C1:C"],[1, 2, 0],"D1:D",
SpreadsheetApp.getActiveSheet())
无法用作自定义函数，应该从另一个函数调用，而不是从公式调用。
