You just need to adjust the table to the way you want it to look. You can create gaps between rows in your table two ways:
1. Setting the height of the row to allow for the appearance of gaps between the text
2. Inserting empty rows in your table between the data rows
The most usual way of presenting data in a table is to set the cell-spacing and cell-padding attributes to the table to (say) cell-spacing 1px, cell-padding 2px, and setting the height of the row and background colour to match your page design.
Alternatively, you can insert empty rows between, so that the data rows have a background colour, and the empty row doesn't.
Or you can have data in the first four rows (or however many) and have an empty row as the last row.
The thing is that however you design it, if you select that as a repeating region, it will repeat that design.
So, if you want: row - gap - row - gap, just create the table with two rows, data in the first row, and leave the second row empty. You can then adjust the height of the empty row to the gap you want between rows.
