## esCalc Structure: The Smart Copying of Formulas

If you enter a formula into a cell in an esCalc spreadsheet, it will automatically appear in each of the cell’s homo-cells and intelligently adapt itself to the new settlement. If you set one of the cell’s properties through a formula, all its homo-cells will receive the property setting simultaneously. Here we’ll disc...

## esCalc Structure: Homologous Relationship

Some data in a spreadsheet contains the same type of topics. Through the structural and hierarchical way, esCalc creates homologous rows and cells – which are called homo-rows and homo-cells – containing data of the same information type. Here’s the explanation of what this homologous relationship is and the advantage ...

## esCalc Spreadsheet Editing: Bands

A band is the elementary structure unit of an esCalc spreadsheet. So editing a band is the basic operation on a sheet. Different from editing records during which you add or delete data, editing a band means reconstructing it. In examples of this article, Ctrl+Enter will be used to insert records. You can learn more fr...
