stenlarsson opened a new issue, #35681:
URL: https://github.com/apache/arrow/issues/35681
### Describe the bug, including details regarding any error messages,
version, and platform.
In some situations we end up with an empty table. When trying to create a
new table based on this it crashes. Here is the simplest example I can think of:
```ruby
require 'arrow'
array = Arrow::Int64DataType.new.build_array([1])
table = Arrow::Table.new('foo' => array)
empty_table = table.filter([false])
empty_table.select_columns('foo')
```
This results in the following exception:

```
What happens here is that we end up with a `ChunkedArray` with no `Array`s
inside, and you are not allowed to call `combine` on it. Note that this doesn't
happen if you have a `ChunkedArray` with one empty array.
