No problem.
A table report is for viewing a list of records. There is a button at the top to change the table report into Grid Edit Mode.
A table report an also be used as an embedded Child table on a parent record form. If you edit the form properties for that embedded report you can allow it to go into grid edit mode when the parent record is put into edit mode.
99.9% of the time grid edit is not used as an actual saved report. People go into grid edit mode while viewing a table report in order to do the editing and then they save.
