L’élément Table Attributaire

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 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):

Propriétés principales

The Main properties group of the attribute table provides the following functionalities (see figure_layout_table_ppt):

Attribute table Main properties Group

• 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 ^{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 Generate an atlas option in the Atlas panel (see Générer un Atlas), 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.

  Dans la section Colonnes, vous pouvez :

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

  • Remove an attribute with the 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.

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

  • select a row in the list and use the and 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.
