automatic numbering table cells

Using Writer I have a table of 3 columns and 30 rows. How can I automatically number the rows in the first column? (I’m still fairly new to this program so, please, be gentle!)

Please have a look at
Is there any function that can number table-rows in Writer?

Select your entire table
Right click on it
Select Format Number
Choose what you need

… and have fun!

In LibO the context menu is pretty good. I use it very often and can do what is needed.

Was I gentle enough?
