octave> version
ans = 8.4.0

octave> dataframe({"Date", "pow"; "2023-12-14", 0; "2023-12-15", 1; "2023-12-16", 2})
ans = dataframe with 3 rows and 2 columns
_1       Date    pow
Nr       char double
1 2023-12-14      0
2 2023-12-15      1
3 2023-12-16      2

octave> dataframe({"Date"; "2023-12-14"; "2023-12-15"; "2023-12-16"})
ans = dataframe with 2 rows and 1 columns
_1       Date
Nr       char
1 2023-12-15
2 2023-12-16

In the first example, a dataframe with three rows is created. In the second one, the first row is missing. Apparently, this happens whenever rows are made of strings only.
