Tables.kt

Tables.kt is a lightweight Kotlin-Multiplatform library to work with tables of any origin. It is not intended as an alternative to DataFrame library. On the contrary, you can use it together with the provided module. The aim of this library to provide an API for a various tables and row lists.

Another aim is to provide integration between different types of tables. For example load database table with Exposed and convert it to a DataFrame.

The performance could vary depending on the type of the table. For example row-based access to column-based table could be slow and vise-versa. Though in principle, the implementations could be tweaked to be very fast.

The library is intended as multiplatform. It supports JVM, JS-IR and Native targets.
