Names default to here(1);
dt = New Table( "Untitled 231",
Add Rows( 1 ),
New Column( "ID", Set Values( [1] )),
New Column( "Row1", character, Set Values( {"a"} )),
New Column( "Row2", character, Set Values( {"b"} )),
New Column( "Row3", character, Set Values( {"c"} )),
New Column( "Row4", character, Set Values( {"d"} )),
New Column( "Row5", character, Set Values( {"e"} )),
);
partial_column = function({searchtxt, dt=currentdatatable()},
{default local},
allCols = dt << GetColumnNames("String");
filtered_list = {};
for(i=1, i<=nitems(allCols), i++,
if(isstring(regex(allCols[i], searchtxt)),
insert into(filtered_list, allCols[i]);
);
);
return(filtered_list);
);
dt << Combine Columns(
Columns(partial_column("Row.")),
Column Name( "ALL" ),
Delimiter( " " )
);
