Sheet (Excel Write/Read Framework 0.4.8 API)

java.lang.Object
- org.ttzero.excel.entity.Sheet

所有已实现的接口:

Cloneable, Storable

直接已知子类:

CollectionSheet, CSVSheet, EmptySheet, ListSheet, ResultSetSheet
```
@TopNS(prefix={"","r"},
       value="worksheet",
       uri={"http://schemas.openxmlformats.org/spreadsheetml/2006/main","http://schemas.openxmlformats.org/officeDocument/2006/relationships"})
public abstract class Sheet
extends Object
implements Cloneable, Storable
```
Each worksheet corresponds to one or more sheet.xml of physical. When the amount of data exceeds the upper limit of the worksheet, the extra data will be written in the next worksheet page of the current position, with the name of the parent worksheet. After adding "(1,2,3...n)" as the name of the copied sheet, the pagination is automatic without additional settings.
Usually worksheetWriter calls the nextBlock() method to load a row-block for writing. When the row-block returns the flag EOF, mean is the current worksheet finished written, and the next worksheet is written.
Extends the existing worksheet to implement a custom data source worksheet. The data source can be micro-services, Mybatis, JPA or any others. If the data source returns an array of json objects, please convert to an object ArrayList or Map ArrayList, the object ArrayList needs to extends ListSheet, the Map ArrayList needs to extends ListMapSheet and implement the ListSheet.more() method.
If other formats cannot be converted to ArrayList, you need to inherit from the base class Sheet and implement the resetBlockData() and getHeaderColumns() methods.
