The custom view supports column formulas, which include support for CalcEngine Functions. Other columns can be referenced using a structured reference like "=[@column1]";
This is the sample code.
The reference is consist of at least one row ref or column ref.

Description
Sample
Current Row
Reference the current row
[@column1] the data in the current row of field column1
Relative Row
Reference the relative row
[@+1column1] returns column1 value in the next row [@-1column1] returns column1 value in the previous row.
Absolute Row
Reference the row of absolute position by row number or "last"/"odd"/"even"
[#1[column1]] returns column1 values in first row. [#last[column1]] returns column1 value in the last rows
Absolute Row by ID
Reference the row by the primary key
[$1234[column1]] returns column1 values of data with primary key "1234"
Row Range
Reference the range of rows by from and to
[@:#last[column1]] returns column1 values of rows from current row to the last row
Several Rows
Reference several rows by comma
[#1,@-1:@+1,#last[column1]] returns column1 values in first row, previous row to the next row, and the last row.
