RecyclerView with horizontal and vertical scroll and fixed header on top and left

Question

I have to implement a table like this, but I don't know how to handle all these scroll behaviors:

Second image

Third image

I was already able to implement the table with all the values and the fixed header, but I am not able to fix the two columns at the left. This is my layout:

<HorizontalScrollView
        android:layout_width="match_parent"
        android:layout_height="@dimen/dimen_0"
        android:layout_marginStart="@dimen/dimen_20"
        android:layout_marginTop="@dimen/dimen_20"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/operations_table_toolbar"
        app:layout_constraintVertical_bias="0.0">

        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="wrap_content"
            android:layout_height="match_parent">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/header_recycler_view"
                android:layout_width="@dimen/dimen_0"
                android:layout_height="@dimen/dimen_30"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent" />

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/rows_recycler_view"
                android:layout_width="wrap_content"
                android:layout_height="@dimen/dimen_0"
                android:layout_marginTop="@dimen/dimen_20"
                app:layout_constraintBottom_toBottomOf="parent"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toBottomOf="@id/header_recycler_view" />
        </androidx.constraintlayout.widget.ConstraintLayout>
    </HorizontalScrollView>

The first recycler view is for the header views, where I am handling different types of views. The second one is a recycler view of recycler views.

Has someone a suggestion on how to do something like that? With ItemDecorators, CustomLayoutManagers, or something like that? The elevations are not important, but it is nice to have them.

Thanks in advance.
