Use the function settings in Tables and Borders.
1, first make a table with many squares (for example, 20 rows and 25 columns), try to see if the result is square and then determine how many rows and columns.
2. According to the shape of the word "Tian", select some lines for many times, and the border is set to "no border".
3. Similarly, set some columns as borderless.
Preview it first. Isn't it convenient and amazing? !
The key here is to master the buttons like the word "Tian" in the shortcut menu of the table and its small downward arrow on the right. All the mysteries are inside. Of course, it is necessary to combine the presence, thickness and virtual reality of the "line type" in front.
If you master the method, four-wire grid and Mi Zige will follow suit.
