How can i adjust all the content to the block In a table ?

Well, then the next question is:

Did you ever try scripting InDesign with ExtendScript ( JavaScript ) ?

Or do you have at least some experience in JavaScript?

The code below is written in ExtendScript ( JavaScript ) and will give you an array of all graphics that are placed directly to graphic cells in the first column of a selected table. To run the code you have to save it as plain text file with a *.jsx suffix and place the file into the folder that you can access from InDesign's Scripts Panel User folder.

And you have to select the table in your document.

To understand the code will be the precondition to go from there. So also read all my comments in the code below.

It's a good starting point to get access to all the graphics ( or images ) you want to work with:

	To select a table:
	Select a cell and do Selct All
	
	To select a graphic cell select the container frame in the cell and type: Esc
	To select a text cell select some text in the cell and type: Esc

( function()
{
	// If no document is open, do nothing:
	if( app.documents.length == 0 ){ return };

	// If no table is selected, do nothing:
	if( app.selection.length != 1 ){ return };
	if( app.selection[0].constructor.name != "Table" ){ return };
	
	// No graphic cells available with your version of InDesign? Do nothing:
	if( !app.selection[0].cells[0].hasOwnProperty("cellType") ){ return };


	var myTable = app.selection[0];

	var myGraphicsArray = myTable.columns[0].cells.everyItem().allGraphics ;

	// IMPORTANT: Flatten array of arrays to get an array of graphics and images:
	myGraphicsArray = [].concat.apply( [] , myGraphicsArray );
	
	// Now loop the array to filter the right graphics:

	for( var n=0; n<myGraphicsArray.length; n++ )
	{
		var graphic = myGraphicsArray[n];
		var graphicContainer = graphic.parent ;
		var outerContainer = graphicContainer.parent ;
		
		// Check if the graphic or image is placed directly in a graphic cell:
		// That will EXCLUDE graphics that are grouped and pasted inside the graphic frame of a graphic cell.
		if
		( 
			outerContainer.constructor.name == "Cell" && 
			outerContainer.cellType == CellTypeEnum.GRAPHIC_TYPE_CELL 
		)
		{
			// NOW DO SOMETHING TO:
			
			// The graphic container holding the image
			// The graphic itself
			// The outer container, which is the graphic cell
			
			// EG FIT THE GRAPHIC TO ITS CONTAINER LIKE SO:
			
			// The graphic or image will not be cropped:
			graphicContainer.fit( FitOptions.PROPORTIONALLY ); 
			
		};
	};

}() )

For ExtendScript development on Windows use the ExtendScript Toolkit App, short the ESTK.

With the latest Mac OS X the ESTK is not available anymore. Even with previous versions of OS X there is a serious bug in the ESTK so it's better to look after a substitution for the ESTK like the Adobe ExtendScript Debugger for Visual Studio Code on Mac OS X.

What's your version of InDesign?

Did you consider using graphic cells for the cells with the images?

Or even better: Are all of your images placed in graphic cells?

How do you decide if an image should be scaled to 100% ?

And if the image is scaled, is it ok to crop the graphic because the height or width of the cell cannot show the whole graphic?
