Interface FlatTable

All Superinterfaces:

ReportComponent

public interface FlatTable
extends ReportComponent

This is a normal tabular report (don't get confused by its name)

The layout of a flat table looks like:

Column 1	Column 2	column 3	column 4	column 5
data 11	data 12	data 13	data 14	data 15
data 21	data 22	data 23	data 24	data 25
data 31	data 32	data 33	data 34	data 35

The mandatory settings of a flat table are:

1. data columns
2. table input

The optional settings are:

1. group columns
2. sorting values
3. showing data
4. showing totals
5. showing grand total

Usually the flat table is used as a component of a report:

 
 FlatTable flatTable = new FlatTableBuilder()
    .input(new TextInput("./inputData/population.csv",","))
    .addDataColumn(new DefaultDataColumn.Builder(0).header("Country").build())
    .addDataColumn(new DefaultDataColumn.Builder(1).header("City").build())
    .addDataColumn(new DefaultDataColumn.Builder(2).header("Population").build())
    .build();
    
 Report report = new ReportBuilder(new DefaultReportOutput(new FileWriter("/tmp/report.html")));
 report.add(flatTable); 
 report.execute(); 

but it can be used also as a stand alone component

  
  FlatTable flatTable = new FlatTableBuilder()
     .input(new TextInput("./inputData/population.csv",","))
     .addDataColumn(new DefaultDataColumn.Builder(0).header("Country").build())
     .addDataColumn(new DefaultDataColumn.Builder(1).header("City").build())
     .addDataColumn(new DefaultDataColumn.Builder(2).header("Population").build())
     .build();
     
  ReportOutput reportOutput = new DefaultReportOutput(new FileWriter("/tmp/testFlatTable.html"))
  reportOutput.open(); 
  flatTable.output(reportOutput); 
  reportOuptut.close();
