Ab#133813 improve column sizing of custom actions

[GhaziAlibi]

Description

This change resolves a layout issue where custom row action columns (e.g., the "Action" column containing action buttons) generated unnecessary whitespace. This occurred because the column width calculation was based statically on the sum of all configured action buttons, even if only one button was visible at any time per row.
