How to measure a cell width and height in a table or a grid ?

[debdagybra]

How can I get width and height of the cells of a table or a grid in context.

I tried the code below (in typst.app with version 0.11.0) but

• for the whole table, the result is weird.
• when I look at the children, the columns parameter of the table isn't used anymore and the result isn't what I want.

#set page(
    width: 210mm, height: 297mm,
    margin: (left: 2cm, right: 2cm, top: 2cm, bottom: 2cm),
  )

#context [

    #let table_1 = table(
        columns: (1fr, 1fr),
        rect()[#lorem(3)], 
        rect()[#lorem(6)]
      )
      
    #table_1
    table size:         #measure(table_1) \
    left cell size:     #measure(table_1.children.at(0)) \
    right cell size:    #measure(table_1.children.at(1)) \

    #let table_2 = table(
        columns: (2fr, 1fr), // I changed first column to 2fr
        rect()[#lorem(3)], 
        rect()[#lorem(6)]
      )
      
    #table_2
    table size:        #measure(table_2) \
    left cell size:    #measure(table_2.children.at(0)) \
    #text(fill: red, "Not what I expected") 
    right cell size:   #measure(table_2.children.at(1)) \
]

I expected something like right cell size: (width: 140pt, height: 34pt)

Do you have any ideas how I can do it ?
