속성 테이블 항목¶

주요 속성¶

The Main properties dialog of the attribute table provides the following functionalities (see figure_composer_table_ppt):

Attribute table Main properties Dialog

• For Source you can normally select only Layer features.
• With Layer you can choose from the vector layers loaded in the project.
• In case you activated the Generate an atlas option in the Atlas generation panel, there are two additional Source possible:
  • Current atlas feature (see figure_composer_table_atlas): you won’t see any option to choose the layer, and the table item will only show a row with the attributes from the current feature of the atlas coverage layer.
  • and Relation children (see figure_composer_table_relation): an option with the relation names will show up. This feature can only be used if you have defined a relation using your atlas coverage layer as parent, and the table will show the children rows of the atlas coverage layer’s current feature (for further information about the atlas generation, see 지도책 생성).
• The button [Refresh table data] can be used to refresh the table when the actual contents of the table has changed.

• The button [Attributes...] starts the Select attributes menu, see figure_composer_table_select, that can be used to change the visible contents of the table. After making changes use the [OK] button to apply changes to the table. The upper part of the window shows the list of the attributes to display and the lower part helps to set the way the data is sorted.

  • Select a cell in the Width column and change it from Automatic to a width in mm, just type a number. When you want to change it back to Automatic, use the cross.
  • The [Reset] button can always be used to restore it to the original attribute settings.

  Sorting 부분에서 다음 작업을 할 수 있습니다:

  • Add an attribute to sort the table with. Select an attribute and set the sorting order to ‘Ascending’ or ‘Descending’ and press the plus button. A new line is added to the sort order list.

객체 필터링¶

The Feature filtering dialog of the attribute table provides the following functionalities (see figure_composer_table_filter):

Attribute table Feature filtering Dialog

이 대화창에서 다음 작업을 할 수 있습니다:

• Maximum rows 옵션에서 표시할 최대 행 개수를 정의할 수 있습니다.

• Remove duplicate rows from table 옵션을 활성화하면 유일한 레코드만 표시할 수 있습니다.

• Activate Show only visible features within a map and select the corresponding Composer map to display the attributes of features only visible on selected map.

• Activate Show only features intersecting Atlas feature is only available when Generate an atlas is activated. When activated it will show a table with only the features which intersect the current atlas feature.

• Filter with 옵션을 활성화하면 입력 란에 필터를 직접 입력하거나 또는 옆에 있는 버튼을 눌러 정규 표현식을 삽입할 수 있습니다. 다음은 QGIS 예시 데이터셋에서 airports 레이어를 불러온 경우 사용할 수 있는 필터링 선언문의 몇몇 예시입니다:

  • ELEV > 500
  • NAME = 'ANIAK'
  • NAME NOT LIKE 'AN%'
  • regexp_match( attribute( $currentfeature, 'USE' )  , '[i]')

  마지막 정규 표현식은 ‘USE’ 속성 필드에 i 문자가 있는 공항만 포함시킬 것입니다.
