There are several ways that the rows can be added to your report, depending on the situation. Here are the steps on how you can add and remove the row lines.
Adding new rows by creating a new widget
The first option is to drag a new widget into the report and hover it over between other widgets; this will automatically add new rows.
Note: that this works only if you try to add new widgets to the report.
Adding new rows by clicking the plus sign
The second option is to hover to the left side of your report until you see a + sign, which says "Insert line below". Once you click on this option, you will see new lines appearing in the report. Once you make enough space, you will be able to add more widgets to your report in between the ones you already have.
Note: You have to be in edit mode for the "Insert line below" or "Remove line" button to appear
Removing rows
If you want to delete a row, you would have to hover to the left side of the report again until you see an X sign that says "Remove line". By pressing it, the line will be removed.
