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.
