At the table I tried to move the red columns from the right side to the left side with the possibility of rotation.
I tried using the android:gravity="right", but it did without results.
How can I move the green column to the far right side and move the other columns to the left without problems.
Here's a screenshot
My layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:layout_height="wrap_content">

<TableLayout

Gravity is not the solution to this problem, the android:gravity property moves the contents of the element, which is why you can see that all of your 'fixed' texts are aligned to the right hand side of the column.
The order of children in a LinearLayout is solely determined by the order they appear in the layout xml. In a vertical layout they go in order from top to bottom and in a horizontal layout they go in order from left to right. So in your case, if you want to change the order of those columns, you just need to put them in the correct order in your layout:
<LinearLayout android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<HorizontalScrollView
android:id="@+id/scroller"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content">
<TableLayout
android:id="@+id/scrollable_part"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</HorizontalScrollView>
<TableLayout
android:id="@+id/scrollable_part2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
