How To Make A Range In Numbers (iwork) Using Jxa

I'm using JXA for automating a process using Numbers app. What I need is to select a range of cells to apply width, but JXA doesn't allow me to get them. According to apple documen

Solution 1:

This AppleScript:

tell application "Numbers"
    tell table1of sheet 1of document 1set selection rangetorange "A2:A20"
    end tell
end tell

is actually setting the table's selection range to the table's range named "A2:A20".

Here is the equivalent JavaScript:

var Numbers = Application("Numbers")
var table = Numbers.documents[0].sheets[0].tables[0]

table.selectionRange = table.ranges["A2:A20"]
