Allow Table Visuals to Set or Preserve Column Header Height Across Horizontal Scrolling

In Power BI table visuals, long column headers can be displayed in a vertical-like format by enabling text wrapping and setting narrow column widths.

However, when a table contains many columns and the long headers are outside the initially visible area, the column header height appears to be calculated only from the columns visible when the report is first rendered. After scrolling horizontally, the header height is not recalculated, causing long wrapped headers to be clipped.

Example scenario:

・Columns 1–20 use normal horizontal headers with custom widths.
・Columns 21 onward use narrow widths, such as 21–30 px, to display long Japanese headers vertically.
・Only columns 1–20 are visible when the report opens.
・After scrolling to columns 21 onward, the long headers are clipped because the header height remains unchanged.

Please add one or both of the following options:

・Allow users to set a fixed column header height.
・Calculate the column header height based on all columns, including columns outside the initially visible area.

This would improve usability for wide tables that contain a mix of normal and vertically wrapped column headers.
