主题：请问老师，如何才能填充本年的数据？

Dim y As Integer = Date.Today.Year
Dim dt1 As New Date(y, 1, 1)
Dim dt2 As New Date(y, 12, 31)

Dim f As New Filler
f.SourceTable = DataTables("应收明细")
f.SourceCols = "单位名称"
f.DataTable = DataTables("本年应收汇总表")
f.DataCols = "客户名称"   ‘想只在“客户名称”列填充本年的数据，我怎么在MaintableChanged 里改呢？
f.Append=False
f.Fill()
