Hello al,
Hope you're doing well!
I have a problem with array and I don't know how to solve it, I hope someone can help me. I have 5 text files, each one has three columns and several lines (example attached). I'm trying to use a combobox to display only the first column by joining all the rows of the 5 lists.
Sample lists:
I'm trying to make the combobox look like this:
... Adding the missing lines
My problem is that I don't know how to join several 2D arrays and end up with a 2D array with all the lists joined.
I can only show one list in the combobox, but I don't know how to join the other lists in the same combobox.
