El elemento de Tabla de Atributos

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 Generar 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.
