+ * Add a new row to the table containing a summary
+ * of the rows from StartRowToSummarize to EndRowToSummarize.
+ * It then deletes the rows from StartRowToSummarize to EndRowToSummarize.
+ * The new row created has a label = 'other'
+ *
+ * This filter is useful to build a more compact view of a table,
+ * keeping the first records unchanged.
+ *
+ * For example we use this for the pie chart, to build the last pie part
+ * which is the sum of all the remaining data after the top 5 data.
+ * This row is assigned a label of 'Others'.
