This method for you might work. Use a hidden column that has a formula that sets the value in a different column. The column that has the value set remains editable, since it does not contain a column formula.
New Table( "Examplel",
Add Rows( 10 ),
New Column( "Default Row State",
Numeric,
"Continuous",
Format( "Best", 12 ),
Set Values( [., 3, ., ., 44, ., 8, ., ., .] )
),
New Column( "formula column",
Numeric,
"Continuous",
Format( "Best", 12 ),
Formula(
If( Is Empty( :Default Row State ) & :Default Row State != :Formula Column,
:Output Column[Row()] = .,
:Output Column[Row()] = :Default Row State
);
:Formula Column = :Default Row State;
),
Hide
),
New Column( "Output Column",
Numeric,
"Continuous",
Format( "Best", 12 ),
Set Values( [., 3, ., ., 888, ., 8, ., ., .] )
)
)
