属性テーブルアイテム

Any layer in the project can have its attributes shown in the print layout. You can use this to decorate and explain your map with information about underlying data. Use the addTable Add Attribute Table tool following items creation instructions to add a new map item that you can later manipulate the same way as exposed in Interacting with layout items.

By default, a new attribute table item loads first rows of the first (alphabetically sorted) layer, with all the fields. You can however customize the table thanks to its Item Properties panel. Other than the items common properties, this feature has the following functionalities (see figure_layout_table):

  • For Source you can by default only select Layer features allowing you to select a Layer from the vector layers loaded in the project.

    The dataDefined data-defined override button near the layer list allows you to dynamically change the layer which is used to populate the table, e.g. you could fill the attribute table with different layer attributes per atlas page. Note that the table structure used (column settings) is the one of the layer shown in the Layer drop-down list and it is left intact, meaning that setting a data defined table to a layer with different field(s) will result in empty column(s) in the table.

    In case you activate the checkboxGenerate an atlas option in the Atlas panel (see 地図帳を作成), there are two additional Source possible:

    • Current atlas feature (see figure_layout_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_layout_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.

  • 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 dialog, (see figure_layout_table_select) that can be used to change the visible contents of the table. The upper part of the window shows the list of the attributes to display and the lower part helps you sort the data.

    属性テーブル 属性選択ダイアログ

    セクションでは:

    • Move attributes up or down the list by selecting the rows and then using the arrowUp and arrowDown buttons to shift the rows. Multiple rows can be selected and moved at any one time.

    • Add an attribute with the signPlus button. This will add an empty row at the bottom of the table where you can select a field to be the attribute value or create an attribute via a regular expression.

    • Remove an attribute with the signMinus button. Multiple rows can be selected and removed at any one time.

    • Reset the attribute table back to its default state with the Reset button.

    • Clear the table using the Clear button. This is useful when you have a large table but only want to show a small number of attributes. Instead of manually removing each row, it may be quicker to clear the table and add the rows needed.

    • Cell headings can be altered by adding the custom text in the Heading column.

    • Cell alignment can be managed with the Alignment column which will dictate the texts position within the table cell.

    • Cell width can be manually managed by adding custom values to the width column.

    並べ替え セクションでは:

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

    • select a row in the list and use the arrowUp and arrowDown buttons to change the sort priority on attribute level. Selecting a cell in the Sort Order column helps you change the sorting order of the attribute field.

    • use the signMinus button to remove an attribute from the sort order list.

地物フィルタリング

The Feature filtering group of the attribute table provides the following functionalities (see figure_layout_table_filter):

機能は:

  • 最大行数 で表示行を指定します.

  • checkbox テーブルから重複行を削除する をチェックすると, ユニークレコードのみ表示されます.

  • Activate checkbox Show only visible features within a map and select the corresponding Linked map whose visible features attributes will be displayed.

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

  • checkbox フィルタ ではフィルタ機能が提供されます。入力行に直接入力するか、 expression ボタンから通常の式を挿入します。サンプルデータセットから空港レイヤーをロードしたとき使用できるいくつかのフィルタ式の例があります:

    • ELEV > 500

    • NAME = 'ANIAK'

    • NAME NOT LIKE 'AN%'

    • regexp_match( attribute( $currentfeature, 'USE' ) , '[i]')

    最後の式では、属性フィールド「USE」に文字「i」が含まれる空港だけを抽出しています。
