implements IfFormatOneLineHeaderExcelTableReader<org.apache.poi.ss.usermodel.Cell>, IfDataTypeCellExcelTableReader

Reads tables with known number of columns, known header labels and known start position of the table.

It obtains cell values as Cell object.

The header line is required. This class reads the table at the designated position and designated lines and columns.
Finish reading if all the columns are empty in a line.

Constructor Details

CellOneLineHeaderExcelTableReader

public CellOneLineHeaderExcelTableReader(@RequireNonnull
 String sheetName,
 @RequireNonnull
 String[] headerLabels,
 @Nullable
 Integer tableStartRowNumber,
 int tableStartColumnNumber,
 @Nullable
 Integer tableRowSize)

Constructs a new instance. the obtained value from an empty cell is null.

tableColumnSize is not designated because tableColumnSize of the table is obviously equal to the length of the header array.

About the params sheetName, tableStartRowNumber, tableStartColumnNumber, tableRowSize and tableColumnSize, see ExcelTableReader(String, Integer, int, Integer, Integer).

Method Details

getFarLeftAndTopHeaderLabel

@Nonnull
public String getFarLeftAndTopHeaderLabel()

Description copied from interface: IfExcelTable

Returns the value of the far left and top header cell to specify the position of the table.

The method is called when tableStartRowNumber is null.

So always set non-null tableStartRowNumber value when the table doesn't have a header.
