Manually moving rows in a table

waiting foe MS to develop what you nedde, give a try to this  function:

let
    moveRow = (tab,row, posToMove)=>
    let 
    Pos=Table.PositionOf(tab,row),
    fromPos=Table.RemoveMatchingRows(tab,{row}),
    toPos=Table.InsertRows(fromPos,Pos+posToMove,{row})
    
    in 
        toPos
in
    moveRow

if you have a table like this and want to move row [col1=22,col2=bb] two position down

you can call the function and get this

if you want to move row [col1=33,col2=cc] two positio up (use a negative relative position)

it is possible using this scheme to add also the management of moving whatever row from pos Pi to position Pf
