1. Column A automatically displays the problem: the simplest thing is to enter the formula "=if(and($h 1<> in A1"j1<>"Unknown",if($h1<>"It worked",if($j1<>"Invalid","Copy this formula for the cells below it; You can also enter the formula unknown in any cell in column A",if(indirect("$h"&row()) works",if(indirect("$j"&row()) is invalid","Copy this formula for the rest of the cells that are also to be displayed automatically.
2. The problem of automatic display of K columns: the simplest thing is to enter the formula "=if(and($b 1<> in the K1 of Xunkong Bend"d1<>"e1<>"Class A","Mu stuffy"Copy this formula for the cells below it; You can also enter a formula class in any cell of column k","Copy this formula for the rest of the cells that are also to be displayed automatically.
3. Create a marker column, such as column L, enter the formula "=$b 2&$d 2&$e 2" in L1, then select column B, column D, column E (press the Ctrl key, click the column label position with the mouse to select), then click the 'Data Validity' button in the data menu, select 'Allow' in the 'Allow' tab of the open data validity dialog box, and enter the formula in the 'Formula' If you encounter a prompt: "The formula currently contains an error." Do you want to continue? and select Yes); Then, in the 'Error Warning' tab of the Data Validity dialog box, select 'Warning' for 'Style', set 'Title' to 'Prompt', and set 'Error Message' to 'Duplicate Found'. ', OK to exit. After the above settings, when the content of the three columns is the same, a prompt box will appear, and the prompt content will be "Duplicate found.
Do you want to continue? There are four buttons in the prompt box: 'Yes', 'No', 'Cancel', and 'Help', select 'Yes' to continue the operation, and 'No' needs to be revised.
4. The simpler way is that as long as you close the file, filter the K column to "Class A" and then save the closed file, the K column will only show "Class A" when you open it next time.

DateDiF() is a function to compare the value of the date difference, the usage is: =datedif(start date, end date, parameter), the parameter in this formula is an array, so =datedif(b7,c7,) returns the number of days between b7 and c7 regardless of the number of years and the number of years, that is, {day, year} such an array, where {} is the array symbol, datedif(b7,c7,)*
What this function does is differentiate the date by the number of days - because its yd (day) is exactly *1 and y (year) is exactly *365
text(b7:c7,"md"-229=0 is a Bollinger value with a value of true or false
The () function is to convert a text value or a logical value into a number such that --(text(b7:c7,"md"-229=0) can be a number, if true, it will return 1, if it is fasle, it will return 0
sumproduct() multiplies the corresponding elements in the array and returns the sum of the products. (sumproduct(--text(b7:c7,"md"-229=0))>0), which is actually used to find the number of days from b7 to c7 equal to 229 days.
Note: b7:c7 is a region, which itself is a one-dimensional array.
I tested it, and the part I drew was wrong, please check if it's abnormal when you use it.
