Shure.
Maybe you must call the snippet recursively to find out the last parent:
a table can be in a frame, which can be in a section and so on.

if (object instanceof XTextRange) {
	
	XPropertySet xPropertySet = (XPropertySet) 
UnoRuntime.queryInterface(XPropertySet.class, object);
	XPropertySetInfo xPropertySetInfo = xPropertySet.getPropertySetInfo();


	/*
	* check if xTextRange resides in sidea cell, a section or a frame
	*/

	XTextSection xTextSection = null;
	XTextFrame xTextFrame = null;
	XCell xCell = null;
	// getPropertyValue gives either null  or adequate object

	if (xPropertySetInfo.hasPropertyByName("TextSection")) {
		xTextSection = (XTextSection) 
UnoRuntime.queryInterface(XTextSection.class, 
xPropertySet.getPropertyValue("TextSection"));
	}
	if (xPropertySetInfo.hasPropertyByName("TextFrame")) {
		xTextFrame = (XTextFrame) UnoRuntime.queryInterface(XTextFrame.class, 
xPropertySet.getPropertyValue("TextFrame"));
	}
	if (xPropertySetInfo.hasPropertyByName("Cell")) {//or TextTable
		xCell = (XCell) UnoRuntime.queryInterface(XCell.class, 
xPropertySet.getPropertyValue("Cell"));// or TextTable
	}
}
