This page provides a LibreOffice Basic macro procedure that sorts a table based on the values in multiple columns. It is an example drawn from Chapter 13 ("Calc as a Database") of the 7.0 Calc Guide.
A range can be sorted using up to three columns or rows in a macro. Sorting with extra columns or rows is as easy as adding extra sort fields to a sort descriptor. The macro below uses the class grade sheet in cells $Sheet1.A1:H11 of the linked spreadsheet to illustrate how to sort by two columns. The records are sorted in ascending order, first by Quiz #1 scores and then by Quiz #2 scores.
Sub SortByQuizScores Dim oSheet Dim oRange Dim oSortFields(1) as new com.sun.star.util.SortField Dim oSortDesc(0) as new com.sun.star.beans.PropertyValue oSheet = ThisComponent.Sheets(0) REM Set the range on which to sort oRange = oSheet.getCellRangeByName("A1:H11") REM Sort by the Quiz #1 field in the range oSortFields(0).Field = 4 oSortFields(0).SortAscending = True oSortFields(0).FieldType = com.sun.star.util.SortFieldType.NUMERIC REM Sort by the Quiz #2 field in the range oSortFields(1).Field = 5 oSortFields(1).SortAscending = True oSortFields(1).FieldType = com.sun.star.util.SortFieldType.ALPHANUMERIC REM Set the sort fields to use oSortDesc(0).Name = "SortFields" oSortDesc(0).Value = oSortFields() REM Now sort the range! oRange.Sort(oSortDesc()) End SubThis Calc spreadsheet contains the above LibreOffice Basic code.
