Custom line/row separator

[sibiarunachalam]

This is my table format

id   column1        column2                    column3          
---- --------------- ------------------------------ ------------------ 
 1   data11       data12                           data13
 2   data21       data22                           data23
 3   data31       data32                           data33
 4   data41       data42                           data43

I need to have empty line between each record to view the data clearly.

So what you want is

id   column1        column2                    column3          
---- --------------- ------------------------------ ------------------ 
 1   data11       data12                           data13

 2   data21       data22                           data23

 3   data31       data32                           data33

 4   data41       data42                           data43

?

Yes @freva

It would be even helpful if that is configurable so that line separator can be anything. It would also help to format the span rows.

@sibiarunachalam there are a few ways to achieve this. You can convert the table to rows and then programatically insert empty lines wherever you need them. Another option is to think of the of the empty rows as a row border made out of spaces, e.g.:

String[] headers = {"id", "column1", "column2", "column3"};
String[][] data = {{"1", "data11", "data12", "data13"},
        {"2", "data21", "data22", "data23"},
        {"3", "data31", "data32", "data33"},
        {"4", "data41", "data42", "data43"}};
Character[] style = {null, null, null, null, null, ' ', null, null, '-',
        ' ', null, null, ' ', null, null, ' ', ' ', null, null, null, null, null, null, null, null, null, null, null, null};
System.out.println(AsciiTable.getTable(style, headers, null, data));

Produces

 id   column1   column2   column3 
---- --------- --------- ---------
  1    data11    data12    data13 
                                  
  2    data21    data22    data23 
                                  
  3    data31    data32    data33 
                                  
  4    data41    data42    data43

Thanks @freva for your valuable feedback. Second option will solve the problem in this scenario.
Earlier I tried same approach, but it doesn't work in Windows environment whereas it worked in Linux environment. I think I didn't configure the border style properly.
