any
Returns true if at least one element in this DataColumn satisfies the given predicate.
This is a convenience alias that delegates to Iterable.any on the column's values.
For more information: See any on the documentation website.
Return
true if at least one element matches the predicate, false otherwise.
Parameters
A lambda function that takes a value from the column and returns true if it matches the condition.

Returns true if at least one row in this DataFrame satisfies the given 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. See any on the documentation website.
Example
// Check if there is at least one row where "age" is greater than 18
val hasAdults = df.any { age > 18 }Return
true if at least one row satisfies the predicate, false otherwise.
