I. Overview
1. Expected effect
Sometimes we need to select different parameters and present different template content. For example, according to the summary type selected by the radio button group, the query displays different summary reports. As shown below:
2. Implementation ideas
Users need parameter widgets to control the display of different columns in the report. There are two ways to achieve this:
Method 1: Use conditional attributes to control the report to display different columns.
Method 2: Control the report to display different columns through SQL statements.
II. Example 1: Realize through condition formatting
1. Prepare data
New data set ds1: SELECT * FROM Sales_Volume
2. Make a template
Drag the fields of region and salesperson into the cell, and set different sales summation and report style design respectively. As shown below:
3. Add parameter widget
First add the template parameter type , as shown in the following figure:
Add a "Radio Button Group"widget and "Search"widget in the parameter panel . The widget name of the radio button group widget istype . Set the Data Dictionary and customize the two options, as shown in the following figure:
4. Setting condition formatting
Select cells A1 and A2, right-click to add Conditional Formatting: set the Row Height to 0, and the Formula Condition to $type!='Region' . Select cells A3 and A4, and also add Conditional Formatting: the Row Height is 0, and the Formula Condition is $type!='Salesperson' . As shown below:
Save the template and click "Pagination Preview" to achieve the effect.
5. Effect preview
