У меня есть следующий код VBA, который читает несколько таблиц Excel и сортирует данные. Я хочу внести изменения в код, чтобы он заменял нулевые значения в ячейках последним ненулевым значением.
Это код.

, поэтому он скопировал последнее значение и заменил все нулевые значения на него.
Положение, где начинаются нулевые термины, различно для разных столбцов, поэтому я не уверен, как заставить VBA распознать точку, в которой ячейки стремятся к нулю, а затем как дать ему команду скопировать и заменить нулевые значения на последняя ненулевая ячейка.
