Đây là một trong loạt bài viết chi tiết các giải pháp được gửi đến cho thử thách Podcast 2316.

YouTuber Rico S đã có một cách tiếp cận hoàn toàn khác. Bảng của anh ấy được tạo bởi một công thức mảng động duy nhất.

Một mảng động

Tổng số O không được điền vào. Nếu bạn đã có Charles Williams Speed Tools V4, bạn có thể đưa công thức của Rico vào TOTALS như hình dưới đây.

Cập nhật! Ở trên, tôi đã sử dụng hàm Charles Williams HTOTALS để cải thiện công thức của Rico. Rico nghiên cứu tài liệu cho phần bổ trợ FastExcel và tìm thấy hai chức năng tuyệt vời: SETMEM và GETMEM. Bạn có thể tối ưu hóa công thức của mình bằng cách lưu trữ và truy xuất kết quả của các biểu thức tính toán chuyên sâu được sử dụng nhiều lần trong một công thức. Đây là một chức năng đột phá.

Rico đã sử dụng nó để giảm công thức 6.866 ký tự của mình thành công thức 593 ký tự:

=HTOTALS(CHOOSE((1,2,3,4,5,6),SETMEM(LEFT(SETMEM(LISTDISTINCTS(TRANSPOSE($A$4:$A$9)&":"&TRANSPOSE(FILTER($A$3:$Z$3,LEFT($A$3:$Z$3,8)="Employee")),,,FALSE),"A"),FIND(":",GETMEM("A"),1)-1),"B"),SETMEM(RIGHT(GETMEM("A"),LEN(GETMEM("A"))-FIND(":",GETMEM("A"),1)),"C"),INDEX(UglyData,MATCH(GETMEM("B"),$A$4:$A$9,0)+1,MATCH(GETMEM("C"),$A$3:$Z$3,0)+1),INDEX(UglyData,MATCH(GETMEM("B"),$A$4:$A$9,0)+1,MATCH(GETMEM("C"),$A$3:$Z$3,0)+2),INDEX(UglyData,MATCH(GETMEM("B"),$A$4:$A$9,0)+1,MATCH(GETMEM("C"),$A$3:$Z$3,0)+3),INDEX(UglyData,MATCH(GETMEM("B"),$A$4:$A$9,0)+1,MATCH(GETMEM("C"),$A$3:$Z$3,0)+4)))

Đọc thêm về SETMEM và GETMEM tại đây.

Charles Williams đã đăng ký và đề xuất công thức này:

=HTOTALS(VSTACK(HSTACK(,A4:A9,G3,SLICES(A4:AB9,0,H4:K4)),HSTACK(,A4:A9,L3,SLICES(A4:AB9,0,M4:P4)),HSTACK(,A4:A9,Q3,SLICES(A4:AB9,0,R4:U4)),HSTACK(,A4:A9,V3,SLICES(A4:AB9,0,W4:Z4))))

Vào ngày 19 tháng 3 năm 2020 sau khi hàm LET ra mắt trong Excel, Rico S đã gửi công thức ngắn hơn này. Điều này hiện yêu cầu Office 365 với Insiders Fast.

=LET( _splitChar,"~", _categories,$A$4:$A$9, _colHdrs,$A$3:$Z$3, _employees,FILTER(_colHdrs,LEFT(_colHdrs,8)="Employee"), _unique2DTable,_categories&_splitChar&_employees, _cntE,COUNTA(_employees), _cnt,COUNTA(_unique2DTable), _uniqueList,INDEX(_unique2DTable,INT(SEQUENCE(_cnt,1,0,1)/_cntE+1),MOD(SEQUENCE(_cnt,1,0,1),_cntE)+1), _category,LEFT(_uniqueList,FIND(_splitChar,_uniqueList,1)-1), _employee,RIGHT(_uniqueList,LEN(_uniqueList)-FIND(_splitChar,_uniqueList,1)), _row,MATCH(_category,_categories,0)+1, _col,MATCH(_employee,_colHdrs,0), _Q1,INDEX(UglyData,_row,_col+1), _Q2,INDEX(UglyData,_row,_col+2), _Q3,INDEX(UglyData,_row,_col+3), _Q4,INDEX(UglyData,_row,_col+4), _totalCol,INDEX(UglyData,_row,_col), _finalTable,CHOOSE((1,2,3,4,5,6,7),_category,_employee,_Q1,_Q2,_Q3,_Q4,_totalCol), SORT(_finalTable,2) )
