In Numbers I am trying to sort a table.

I have two issues here. In "Numbers" I am trying to sort a table. I could not find the "Sort" button" easily. Eventually I clicked on "Organize" then on "Show Sort Options". I then chose "Sort Entire Table", "Column A", Ascending". First issue - I used to find the "Sort" button easily before, now I had to search for it. Is there an easy way to find "Sort" without wasting time having to search? Second issue - I was not able to sort because the green "Sort Now" button would not get highlighted. What am I doing wrong? Thanks in advance for any info.
