|---|---|---|---|---|
| TableWorkspace | InOut | TableWorkspace | Mandatory | The name of the workspace that will be modified. |

Example
t=WorkspaceFactory.createTable()
t.addColumn("double","A")
t.addColumn("double","B")
t.addColumn("double","BError")
for i in range(20):
t.addRow([i,i*2,1])
#add it to the Mantid workspace list
mtd.addOrReplace("myTable",t)
#delete a single row
DeleteTableRows(t,Rows=0) #The row index starts at 0
#delete a List of rows, you can also refer to the workspace using the name in the Workspace List
DeleteTableRows(t,Rows=[2,4,6,8]) #Note: the previous delete will have moved all the rows up 1
#delete a range of rows, you can also refer to the workspace using the name in the Workspace List
DeleteTableRows("myTable",Rows=range(7,14))
print "The remaining values in the first column"
print t.column(0)
Output:
The remaining values in the first column
[1.0, 2.0, 4.0, 6.0, 8.0, 10.0, 11.0, 19.0]
