If I understand you correctly, maybe something like this?
If(Key=Previous(Key), 1, 2) as ID_Key,
(ooxml, embedded labels, table is Sheet1, filters(
Replace(1, top, StrCnd(null)),
Replace(3, top, StrCnd(null))
If(IterNo()=ID_Key, Key) as Key,
If(IterNo()=ID_Key, Timestamp(Timestamp), Name) as Timestamp
DROP Table Table1;
Format Timestamp determine what you need.
i want to have this:
12345 01.02.2017 05:00 Alex 12345 01.02.2017 05:30 Alex 12345
If there is in same 'Key' two lines with the same "Name" and empty 'Name' between the 'Timestamp', it should fill up the "Name".
