What is a table resize handle?

A table resize handle is a user interface element that allows users to adjust the dimensions of a table or its columns and rows within a software application or web interface. Typically represented as a small square or line at the edge of a column or row, it can be clicked and dragged to increase or decrease the size of that specific element. This feature provides flexibility in organizing and displaying data according to user preferences. Resize handles are commonly found in spreadsheet applications and data management tools.
