Excel table expands automatically but ignores first row with ID-number
I created a flow using this very usefull tutorial on how to get form responses into an excisting excel sheet. I created an excel table and every formula is, therefore, automatically copied down after a response has been sent (so cool!). However, it skips the first column with id numbers (435, 436, 347 for example). I'm not sure what the problem is (power automate or excel?) and how to fix it.
I've tried several things to make it work. For example, at first the first column was just an enumeration column (1,2,3,4), but now I've created a formula in that column (previous + 1). Unfortunately this doesn't change anything. I also moved the column in the document, that doesn't make a difference either.
There is a possibility to fill the column with an expression in Power Automate, but I can't find which expression to use to get a number that is one more than the row above it.
Can someone help me? Either with repairing the excel table so that the numbering continues automatically when adding a row. Or by creating an expression in Power Automate so that the column of numbers continues to add up.
Hopefully I was able to explain it well, thank you in advance for a reaction!
