This is the file. It is supposed to be a worksheet.
There are lots of tables in the file. Each table has 20 blank rows (for 20 students). I need 40 blank rows (for 40 students).
Adding the rows manually is a menially repetitive task. I found a relatively easy method. Select the 20 rows using the mouse, and then right click. Then an option comes up asking if I want to add 20 rows below or not, but it is still a cumbersome process to repeat for all the tables. How do I accomplish this task more easily?
Edit:
I don't know the Apps Script language, but still I stupidly tried the following code:
function myFunction() {
for (let table in DocumentApp.getTables()) {
for (let i = 0; i < 20; i++) {
table.insertTableRow(20);
}
}
It did not work.
