Lai izveidotu rakurstabulu, kurā parādīti pēdējo 4 nedēļu dati (ti, ritošās 4 nedēļas), avota datiem varat pievienot palīga kolonnu, lai atzīmētu ierakstus pēdējās 4 nedēļās, pēc tam ar palīga kolonnu filtrēt datus pagrieziena galds. Parādītajā piemērā pašreizējais datums ir 2019. gada 25. augusts, un rakurstabulā ir parādīti 4 pilnīgi iepriekšējie. Kad laika gaitā tiks pievienoti jauni dati, rakurstabula turpinās izsekot iepriekšējās 4 nedēļas, pamatojoties uz pašreizējo datumu.
Lauki
Parādītajā rakurstabulā avota datos ir četri lauki: Datums, Pārdošana, Nedēļa un Filtrs. Filtrs ir palīgkolonna ar formulu, kas apzīmē pēdējās 4 nedēļas. Nedēļa ir palīga kolonna, kas atgriež pirmdienu par jebkuru norādīto datumu (tikai ērtības labad). Pārdošana ir vērtības lauks, un nedēļa ir pievienota kā rindas lauks, lai grupētu pa nedēļām:
Formula
D5 (nedēļa) izmantotā formula, kas nokopēta, ir:
=B5-WEEKDAY(B5,3)
Šī formula atgriež nedēļas pirmdienu par jebkuru norādīto datumu.
E5 (filtrs) izmantotā formula, kas nokopēta, ir:
=AND(B5>=TODAY()-WEEKDAY(TODAY(),3)-28,B5
This formula checks for dates in the last n weeks. It returns TRUE when a date is in the last 4 complete weeks, and FALSE if not. See the link for a full explanation.
Customizing week count
To customize the weeks displayed, adjust the Filter formula as needed to increase or decrease days. For example, to display the last 6 weeks (42 days), use:
=AND(B5>=TODAY()-WEEKDAY(TODAY(),3)-42,B5
