Power BI Query Editor - Inserting Rows to the Bottom of a Table - powerbi

Question

I have a table that looks like this in Power BI:
CourseID Course
1 Math
2 Cooking
3 English
4 Spanish
I want to insert a row at the bottom that looks like this:
-1 null
I looked at the Microsoft Documentation, but it's not very helpful. Any suggestions?

Answer 1

Figured out what I was doing wrong.
Let's say I wanted to insert a row, at top of a table, named Courses.
The M query would look like this
#Insert Row = Table.InsertRows(#PreviousStepName,0,{[CourseID=-1,Course=null]})
Was not able to get it working if the column name had a space in it, but for best practices, you shouldn't have columns with spaces in the name anyway.

Answer 2

Follow below steps to insert a row to the bottom of a table:
Step 1: Go to the edit query window. select the correct table.
Step 2: Go to the APPLIED STEPS window on the right-hand side. double click on Source.
Step 3: Add the data to each column and press ok.
Note that, this will only add a row to the end of the table.

Answer 3

The accepted answer above by OP works great if you want to insert a row at the top of the table, or if you know the index to insert at. In my case I want to append to the end, and the amount of rows is likely to change in future.
I saw the functions to reverse the rows, so you could reverse the rows, insert at 0, then reverse again, but I found another way:
#"Insert Row" = Table.Combine({#"Previous Step Name",
Table.FromRows(
{{null, "None", true, false}},
{"ID", "Name", "Deleted", "IsIntegration"}
)
})
Basically, you create a new table with Table.FromRows, then use Table.Combine to append it
