The shortcut Ctrl+L is to display the "Create Table" dialog box, which is the same as the shortcut "Ctrl+T".
Example:
Step 1: Click anywhere in the data range, or select the data part you want to create a table;
Step 2: Press the key "Ctrl" from the keyboard and hold it, then click the letter "L" from the keyboard. This will bring up the "Create Table" window;
Step 3: Click "OK" in the "Create Table" window and the data range you selected turns into a table.
If you already created a table, you can resize the table by clicking the right-bottom corner, then hold and drag to the size you need.
