Solution:
Below is the script which adds rows to a data table, saves it to the library, then reload it if you're using the same SBDF file in the dashboard.
Please find the sample dashboard attached to the KB Article.
Input Parameters:
Visuals -- Table Visualization
SBDF -- Data Table
from Spotfire.Dxp.Data import AddRowsSettings
from System.IO import StringReader, StreamReader, StreamWriter, MemoryStream, SeekOrigin
from Spotfire.Dxp.Data import DataType, DataTableSaveSettings
from Spotfire.Dxp.Data.Import import TextFileDataSource, TextDataReaderSettings
textData = "CarMake,Price,Country\r\nMaruti,10000,India\r\n"
stream = MemoryStream()
writer = StreamWriter(stream)
writer.Write(textData)
writer.Flush()
stream.Seek(0, SeekOrigin.Begin)
readerSettings = TextDataReaderSettings()
readerSettings.Separator = ","
readerSettings.AddColumnNameRow(0)
readerSettings.SetDataType(0, DataType.String)
readerSettings.SetDataType(1, DataType.Integer)
readerSettings.SetDataType(2, DataType.String)
textDataSource = TextFileDataSource(stream,readerSettings)
settings = AddRowsSettings(Document.ActiveDataTableReference,textDataSource)
Document.ActiveDataTableReference.AddRows(textDataSource,settings)
