Use system.dataset.fromCSV to specify data types and column headers for your blank dataset like this:

```auto
blankDataset = """#NAMES
Header1, Header2,
#TYPES
d,I
#ROWS,0"""

```

See [Ignition Manual](https://docs.inductiveautomation.com:8443/display/DOC79/system.dataset.fromCSV) for data types, etc.
