how to create a relationship between tables in excel

There are three main methods to establish table relationships in Excel: use VLOOKUP to establish one-to-one relationships, use PowerQuery to merge queries, and use PowerPivot to establish a multi-table relationship model. 1.

During operation, you need to ensure that the matching field is in the first column of the search area, and pay attention to performance optimization problems under large data volumes; 2. PowerQuery is suitable for multi-table merging scenarios that require frequent updates. Data is loaded and merged queries are merged through graphical operations. After setting, it can be refreshed with one click; 3. PowerPivot is used for complex multi-table modeling analysis, importing each table and establishing the primary key and foreign key association in the relationship view, and supports

How to fill a shape with an image in Photoshop

These three methods have their own applicable scenarios.

How to invert colors in Photoshop

The core method of inverting colors in Photoshop is to use the "Inverting" function. The operation steps are: make sure that the layer is a normal layer, press Ctrl I (Windows) or Cmd I (Mac), or use the menu bar "Image" → "Adjust" → "Inverting"; if you need more flexible control, you can use "Curves" to adjust the layer and invert the curve to simulate the inverting effect, and make local adjustments with the mask; if you encounter smart objects or transparent layers that cannot be directly inverted, you can solve the problem by rasterizing the layer or using the adjustment layer, but it is recommended to copy the layer before operation to prevent quality loss.
