A Markdown Table is a simple way to organize and display data in a grid format using plain text. It is created using the Markdown syntax, which allows users to format text easily. Tables consist of rows and columns, where each cell can contain text, links, or images. The structure is defined using pipes (`|`) to separate columns and dashes (`-`) to create headers. Markdown Tables are widely used in platforms like GitHub and Reddit for documentation and content creation. They are easy to read and write, making them a popular choice for developers and writers who want to present information clearly without complex formatting tools.
