The definition of a table in Excel is that the cells contain data that links them together. This means there must be no empty rows or empty columns. But apart from that, you do not need headlines to have a table in Excel. You do not have to “Insert a table” as you can from the Insert menu, but there are other benefits to this.
What is a table
Type text into two cells underneath each other and type one text in the column to the right of one of these. This is a table. You can sort it, filter it and do other complicated operations you can with tables in Excel.
