how to filter first column in uipath .ColumnName is not known
@Ananya1, What exactly you are looking for? If you want to access column from data table then you can use index of the column if column name is unknown.
If you use a Filter Datatable activity, you can filter the first column by passing the number 0 as the parameter for the column name. Then you can filter on it even if you don’t know the column name.
