element in HTML; the TableRow is like a element; But for each cell, you can use various view elements. In this example, each cell uses TextView. Between these rows, there is also a basic View for drawing horizontal lines

TextView Some attributes in

android:layout_column="1": Indicates that the control is placed on the column numbered 1, and the number starts from 0

android:gravity="right": Definition The font is displayed on the right in the parent control

android:stretchColumns="1": Set which columns to automatically stretch. The column ID starts from 0. If there are multiple columns, use "," to separate them. The function here is to allow the second column to expand to all available space

android:shrinkColumns: Set which columns to automatically shrink. The column ID starts from 0. If there are multiple columns, use "," to separate them

android:collapseColumns: Set which columns to automatically hide. The column ID starts from 0. If there are multiple columns, use "," to separate them

By the way: android:layout_span indicates how many columns of space a control occupies

android:background=”#FF909090″
