Markdown Tables are a simple way to display data in a structured format using plain text. They consist of rows and columns, where each row represents a different entry and each column represents a specific attribute of that entry. The table is created using pipes (|) to separate the columns and dashes (-) to create the header row. To create a Markdown Table, you start with a header row that defines the column names, followed by a separator line made of dashes. Each subsequent line represents a new row of data. This format is easy to read and write, making it popular for documentation and note-taking.
