6、e V in VLOOKUP stands for Vertical.SyntaxSyntaxVLOOKUPVLOOKUP(lookup_valuelookup_value,table_arraytable_array,col_index_numcol_index_num,range_lookup)Lookup_value is the value to be found in the first column of the array.Lookup_value can be a value,a reference,or a text string.Table_array is the tab
7、le of information in which data is looked up.Use a reference to a range or a range name,such as Database or List.If range_lookup is TRUE,the values in the first column of table_array must be placed in ascending order:.,-2,-1,0,1,2,.,A-Z,FALSE,TRUE;otherwise VLOOKUP may not give the correct value.If
8、range_lookup is FALSE,table_array does not need to be sorted.You can put the values in ascending order by choosing the SortSort command from the DataData menu and selecting AscendingAscending.The values in the first column of table_array can be text,numbers,or logical values.Uppercase and lowercase
9、text are equivalent.Col_index_num is the column number in table_array from which the matching value must be returned.A col_index_num of 1 returns the value in the first column in table_array;a col_index_num of 2 returns the value in the second column in table_array,and so on.If col_index_num is less
10、 than 1,VLOOKUP returns the#VALUE!error value;if col_index_num is greater than the number of columns in table_array,VLOOKUP returns the#REF!error value.Range_lookup is a logical value that specifies whether you want VLOOKUP to find an exact match or an approximate match.If TRUE or omitted,an approxi
11、mate match is returned.In other words,if an exact match is not found,the next largest value that is less than lookup_value is returned.If FALSE,VLOOKUP will find an exact match.If one is not found,the error value#N/A is returned.RemarksRemarksIf VLOOKUP cant find lookup_value,and range_lookup is TRU
12、E,it uses the largest value that is less than or equal to lookup_value.If lookup_value is smaller than the smallest value in the first column of table_array,VLOOKUP returns the#N/A error value.If VLOOKUP cant find lookup_value,and range_lookup is FALSE,VLOOKUP returns the#N/A value.ExampleExampleThe
