What does the row and column separator mean?

For example, there are the following data:

User1 Account1 Password1

User2 Account2 Password2

User3 Account3 Password3

There are three rows and three columns of data. The first row of user1, account1 and password1 are separated into columns by spaces, so the column separator of the data is space. User1 account1 password1 is one row, and user2 account2 password2 is the next row. Each row is separated into rows by carriage return, so the row separator of the data is carriage return.

Data is divided into rows and columns to facilitate the storage and use of data, such as the login account and password of the website:

Account1 Password1

Account2 Password2

When the system operates to log in to a website, it can directly call the account and password in the same line to log in. If the data is not in the same line, the login will fail.

Note: The number of columns and rows starts at 0.For example, if we want to call "password 2", then the number of columns should be filled in 2 and the number of rows should be filled in 1.
