QProxyStyle control for QTableWidget grid color?

[CJha]

Hi, I am using Qt 6.4.2 and my application style is based on Fusion style. I am subclassing QProxyStyle to implement the required changes when having dark and light palettes as my main application palette. I have implemented changes in my QProxyStyle subclass to deal with border colors using drawPrimitive() function and changing the color of QPalette::Window to my desired border color when the primitive element is either PE_IndicatorCheckBox, PE_IndicatorRadioButton, PE_Frame, etc. This produces the desired result of changing the border color and hence a separation between the widget area and background when the background color is very dark (close to QColor{0, 0, 0}).

However, when my background is very dark my table widget looks like this (the border around the Enabled checkbox is there because I have reassigned the color for QPalette::Window in my drawPrimitive() function when the primitive element is PE_IndicatorCheckBox):

Is there any way I could control the grid color of QTableWidget from my QProxyStyle subclass?

@CJha The grid color of a QTableView is determined by QStyle::SH_Table_GridLineColor
