Following innovations introduced by QGis version 2.12 : as in Excel tables, now you can control the cells setting of the attribute table of a layer . Now you can apply conditional rules on the format implementation of the attribute table. To this end , open the attribute table of a layer . On the right, you will see a new button for the conditional setting.
Click on the button to open the formatting panel.
You can format a particular column or the entire line by selecting Field or Complete Line . For the field, you must indicate which is the field where you want to apply a format condition. To include a formatting rule, click the New Rule button . Then, you will get the conditional rule configuration panel:
You can enter a name, but for now, it is used nowhere . The @value variable represents the value of the cell. You can type directly a condition, for example @value> 3.0 or open the condition assistant by clicking on the button ε .
As in all the classic expressions in QGis, you can refer to other fields of the table. Once the condition is entered , you control the setting in form associated with the lower panel :
The drop-down menu presents some pre-established setting options.
You can control the background colors and characters, add an icon at the beginning of the cell ( from the QGis characters ), and control the formatting and the characters font. For a single column you can enter many implementation formatting rules. In the following example, the wave heights are classified in three groups , each with a different formatting.. The column hour is classified to put in evidence day and night .
Warning: the formatting is saved in the QGis project . If you open the table in another project, it is not taken into account.
