How can I change the number of rows in the table on top of each page? (Copy)

By default, there are 5 rows in this table (Substance, Method, Assay Number, Technician, Date of Assay). There are always 2 columns.

To add rows, click somewhere on the last row of the table and hit ENTER or the ARROW-DOWN button as many times as necessary to add new rows. Make sure you type something in the last row before leaving it, because otherwise it will be removed again.

To remove rows, start by deleting the content of the second column in the row(s) you want to remove. Then select the rows and hit the DELETE button (make sure you include the last row in your selection).
