Scenes:
In Excel I want to display data that is matched by one column to another in Excel. For programmers, it is to left join the data of table B. But how to do it in Excel, I don't want to import the data into the database every time.
That's what the vlookup function in Excel does.
Instructions:
Enter "=vlookup" in a column in Excel, which will raise several parameters to be input by this function
1. Lookup value -- this selects the column to match in the current column
2. Data table -- to select another data range in Excel
3. Serial number -- which column of another Excel species to display
4. Matching conditions - exact match or fuzzy match
After these 4 parameters are selected, the others are realized by stretching.
