Delete all rows on spotfire Data Table Iron python

Question

I was looking for a way to delete rows in my Data table on SPOTFIRE and I didn't find a proper way to do it.

I tried to code a script to do it, but It's too slow and I have more the 20k rows to be deleted.

Does someone have an idea why it's too slow and if there is a another way to do (a faster way)

from Spotfire.Dxp.Data import RowSelection
table=Document.Data.Tables["my Table name"]
i=0
for row in table.GetRows():
  i+=1
  rowToDelete=Document.Data.Tables["my Table name"].Select("[index]="+`i`).AsIndexSet()
  Document.Data.Tables["my Table name"].RemoveRows(RowSelection(rowToDelete))

Answer 1

I found a way which is more simple to do it.

from Spotfire.Dxp.Data import RowSelection, IndexSet
dtTarget = Document.Data.Tables["my Table name"]
dtTarget.RemoveRows(RowSelection(IndexSet(dtTarget.RowCount,True)))
