 When performing non-equi joins (<, >, <=, >=), it's important to understand how column names are assigned in the result.
 
-- The left operand (`x` column) determines the column name in the result.
-- The right operand (`i` column) contributes values but does not retain its original name.
-- By default, `data.table` does not retain the `i` column used in the join condition unless explicitly requested.

-In non-equi joins, the left side of the operator (e.g., `A` in `A >= B`) must be a column from `x`,  
-and the right side (e.g., `B`) must be a column from `i`.  Non-equi join does not support  arbitrary expressions. For example, `on = .(x_col >= i_col)` is valid, but `on = .(x_col >= i_col + 1)` is not.
