showGrid Display Issue in Table when toggle the theme

[CRY-D]

I'm encountering an issue with the showGrid feature in a JTable . Specifically, the problem arises when switching between the dark and light themes.
Initially, the grid lines in the JTable are displayed correctly.
And when I Switch the theme to light, then Switch it back to the dark, I Observe that the grid lines in the JTable not displayed properly or exhibit unexpected behavior.

The Initial state:

when i switch to light:

when switch it back to dark

i've tried booth methods: flatTable.setShowGrid(true);
and the FlatLaf.properties

#@accentColor=#FF3B30
defaultFont=15 RB
h1.font=bold +12
Component.focusWidth=1
Component.borderWidth=1
#Button.acr=10
#TextComponent.arc=10
#Panel.border=com.formdev.flatlaf.ui.FlatBorder
#TableHeader.background=darken(@background,5%)
List.selectionInsets=0,1,0,1
List.selectionArc= 6
ActionPanel.border=com.formdev.flatlaf.ui.FlatBorder
Table.showGrid=true
Table.alternateRowColor=darken(@background,1%)
Table.intercellSpacing=1,1
ScrollBar.showButtons=true

Table.showGrid is not used in FlatLaf properties files.

Use:

Table.showHorizontalLines = true
Table.showVerticalLines = true

But it could be a bug that invoking table.setShowGrid( true ) is lost when switching L&F.
I'll have a look...

If you need a quick solution to have permanent grid lines for a single table:

JTable table = new JTable() {
    @Override
    public void updateUI() {
        super.updateUI();
        setShowGrid( true );
    }
};

A good solution for me, thank you
