## TableLayout 是什么 ##

TableLayout  是表格布局,就是使用表格的方式划分子组件,

个人感觉应该也不是常用的布局,常用的还是选择DirectionalLayout和DependentLayout ,下面了解下它的属性

## TableLayout的自有XML属性 ##

<table> 
 <thead> 
  <tr> 
   <th> <p>属性名称</p> </th> 
   <th> <p>中文描述</p> </th> 
   <th> <p>取值</p> </th> 
   <th> <p>取值说明</p> </th> 
   <th> <p>使用案例</p> </th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td style="vertical-align:top;"> <p>alignment_type</p> </td> 
   <td style="vertical-align:top;"> <p>对齐方式</p> </td> 
   <td style="vertical-align:top;"> <p>align_edges</p> </td> 
   <td style="vertical-align:top;"> <p>表示TableLayout内的组件按边界对齐。</p> </td> 
   <td style="vertical-align:top;"> <p>ohos:alignment_type="align_edges"</p> </td> 
  </tr> 
  <tr> 
   <td style="vertical-align:top;"> <p>align_contents</p> </td> 
   <td style="vertical-align:top;"> <p>表示TableLayout内的组件按边距对齐。</p> </td> 
   <td style="vertical-align:top;"> <p>ohos:alignment_type="align_contents"</p> </td>

   <td style="vertical-align:top;"> <p>integer类型</p> </td>

   <td style="vertical-align:top;"> <p>ohos:column_count="3"</p> <p>ohos:column_count="$integer:count"</p> </td> 
  </tr> 
  <tr>

   <td style="vertical-align:top;"> <p>行数</p> </td> 
   <td style="vertical-align:top;"> <p>integer类型</p> </td> 
   <td style="vertical-align:top;"> <p>可以直接设置整型数值，也可以引用integer资源。</p> </td> 
   <td style="vertical-align:top;"> <p>ohos:row_count="2"</p> <p>ohos:row_count="$integer:count"</p> </td> 
  </tr> 
  <tr> 
   <td style="vertical-align:top;"> <p>orientation</p> </td> 
   <td style="vertical-align:top;"> <p>排列方向</p> </td> 
   <td style="vertical-align:top;"> <p>horizontal</p> </td> 
   <td style="vertical-align:top;"> <p>表示水平方向布局。</p> </td> 
   <td style="vertical-align:top;"> <p>ohos:orientation="horizontal"</p> </td> 
  </tr> 
  <tr> 
   <td style="vertical-align:top;"> <p>vertical</p> </td> 
   <td style="vertical-align:top;"> <p>表示垂直方向布局。</p> </td> 
   <td style="vertical-align:top;"> <p>ohos:orientation="vertical"</p> </td> 
  </tr> 
 </tbody> 
</table>

看完属性之后练习下

### demo练习TableLayout 的使用 ###

先吐槽一下,官方的文档 layout\_alignment 这个属性前面文档都没有说,这里居然写了,后来反复实现发现没有效果,大家都别想我一样傻不拉几的试了很久,再说写的编译器也不会智能提醒的,

### demo1 TableLayout 里面不添加任何属性 ###

<?xml version="1.0" encoding="utf-8"?>
    <TableLayout
        xmlns:ohos="http://schemas.huawei.com/res/ohos"
        ohos:height="match_parent"
        ohos:width="match_parent">
    
        <Button
            ohos:id="$+id:button1"
            ohos:padding="10vp"
            ohos:background_element="#FF1493"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
        <Button
            ohos:id="$+id:button2"
            ohos:padding="10vp"
            ohos:background_element="#FF00FF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
        <Button
            ohos:id="$+id:button3"
            ohos:padding="10vp"
            ohos:background_element="#0000FF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
        <Button
            ohos:id="$+id:button4"
            ohos:padding="10vp"
            ohos:background_element="#00FFFF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
    </TableLayout>

看下效果

### orientation 属性 ###

试下orientation 属性,也不知道是我理解不对还是怎么了,设置horizontal 里面的控件是垂直的,

设置vertical的时候里面控件是水平的看下面的效果图

设置horizontal的情况

设置orientation 的情况

反正大家知道有这个属性就行了(难受)

感觉里面最重要的就是column\_count 和 row\_count,下面看下他两的属性

### demo2 设置 2行 和2列 ###

<?xml version="1.0" encoding="utf-8"?>
    <TableLayout
        xmlns:ohos="http://schemas.huawei.com/res/ohos"
        ohos:height="match_parent"
        ohos:width="match_parent"
        ohos:row_count="2"
        ohos:column_count="2">
    
        <Button
            ohos:id="$+id:button1"
            ohos:padding="10vp"
            ohos:background_element="#FF1493"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
        <Button
            ohos:id="$+id:button2"
            ohos:padding="10vp"
            ohos:background_element="#FF00FF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
        <Button
            ohos:id="$+id:button3"
            ohos:padding="10vp"
            ohos:background_element="#0000FF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
        <Button
            ohos:id="$+id:button4"
            ohos:padding="10vp"
            ohos:background_element="#00FFFF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
    </TableLayout>

### demo3设置1行4列 ###

<?xml version="1.0" encoding="utf-8"?>
    <TableLayout
        xmlns:ohos="http://schemas.huawei.com/res/ohos"
        ohos:height="match_parent"
        ohos:width="match_parent"
        ohos:row_count="1"
        ohos:column_count="4">
    
        <Button
            ohos:id="$+id:button1"
            ohos:padding="10vp"
            ohos:background_element="#FF1493"
            ohos:height="match_content"
            ohos:width="match_content"

            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
        <Button
            ohos:id="$+id:button2"
            ohos:padding="10vp"
            ohos:background_element="#FF00FF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
        <Button
            ohos:id="$+id:button3"
            ohos:padding="10vp"
            ohos:background_element="#0000FF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
        <Button
            ohos:id="$+id:button4"
            ohos:padding="10vp"
            ohos:background_element="#00FFFF"
            ohos:height="match_content"
            ohos:width="match_content"
            ohos:layout_alignment="center"
            ohos:text_size="22fp"
            ohos:text="java"/>
    
    
    </TableLayout>

最后说下column\_count 和 row\_count 使用的时候要注意里面的控件,如果多余你设置的行和列的话默认多余的一个在下面,比如我里面写了6个控件设置2行和2列的效果图

比如下面的
