The zero-based index of the columns to shrink. The column indices must be separated by a comma: 1, 2, 5. Illegal and duplicate indices are ignored. You can shrink all columns by using the value "*" instead. Note that a column can be marked stretchable and shrinkable at the same time.

android:collapseColumns

android:collapseColumns

要折叠的列的从零开始的索引.列索引必须用逗号分隔:1、2、5.非法和重复的索引将被忽略.

  说明:

  android:stretchColumns="*"

  意味着它根据表格布局宽度平均拉伸所有列

  Means it stretch all columns equally according table layout width

  android:shrinkColumns="*"

  意味着它缩小了所有列

  android:shrinkColumns="0,2"

  android:stretchColumns="1"

  表示第 0 列和第 2 列是换行包含，第 1 列拉伸到可用宽度

  Means column 0 and 2 are wrap contain and column 1 stretch into available width

  android:stretchColumns="0,1,2"

  android:shrinkColumns="1"

  表示如果列已经拉伸然后收缩不适用

  Means if column already stretch then shrink not apply

  android:shrinkColumns="*"

  android:collapseColumns="1"

  android:collapseColumns 意味着它隐藏给定的列

  android:collapseColumns means it hide given column

  android:stretchColumns="*"

  TextView :- android:layout_column="2"

  表示如果 tablerow 第一列布局参数不是以 0 开头，则将空视图添加到行中

  Meanning if tablerow first column layout parameter not start with 0 then empty view added into row

  android:stretchColumns="*"

  android:collapseColumns="1"

  TextView :- android:layout_column="2"

  表示如果 tablerow 第一列布局参数不以 0 开头，则将空视图添加到行中，但如果折叠列然后添加空视图，则不会隐藏该列索引，仅通过显式视图隐藏添加的视图

  Means if tablerow first column layout parameter not start with 0 then empty view added into row but if you collapse column then added empty view not hide of that column index only hide added view by explicit view
