dropWhile

Returns a DataFrame containing all rows except the first rows that satisfy the given predicate.

Rows are dropped for as long as the predicate holds; the operation stops at the first row that does not satisfy it, and no later row is dropped even if it satisfies the predicate.

The predicate is a RowFilter — a lambda that receives each DataRow as both this and it and is expected to return a Boolean value.

It allows you to define conditions using the row's values directly, including through extension properties for convenient and type-safe access.

For more information, See RowFilter on the documentation website.

This can include column groups and nested columns.
