No column detected from CSV with no data (header row only) #815
Description
Hi,
I read a CSV file with no data (header row only) and I noticed that no column was detected.
The resulting table is empty.
final ByteArrayInputStream inputStream = new ByteArrayInputStream("Column1;Column2;Column3\n".getBytes(StandardCharsets.UTF_8));
final CsvReadOptions readOptions = ((CsvReadOptions.Builder) CsvReadOptions.builder(inputStream)
.columnTypesToDetect(Arrays.asList(ColumnType.STRING)))
.header(true)
.separator(';')
.build();
final Table table = Table.read().csv(readOptions);
assertThat(table.columns(), hasSize(0)); // OKDid I make something wrong?
Any help would be greatly appreciated.
