如何在不使用重力的情况下移动右侧的第一列 属性？
How can I move the first column on the right side without using gravity property?
在 table 我尝试将红色柱子从右侧移动到左侧，以便旋转。
我尝试使用 android:gravity="right"，但没有结果。
如何将绿色列移动到最右侧并将其他列移动到左侧而没有问题。

Gravity 不是这个问题的解决方案，android:gravity 属性 移动元素的 contents，这就是为什么你可以看到所有您的 'fixed' 文本与列的右侧对齐。
子元素在 LinearLayout 中的顺序完全由它们在布局中出现的顺序决定 xml。在垂直布局中，它们按从上到下的顺序排列，在水平布局中，它们按从左到右的顺序排列。所以在你的情况下，如果你想改变这些列的顺序，你只需要在你的布局中以正确的顺序放置它们：
<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>
