Resize width of all inline images in tables

I see. I've had a re-think and here's a possible solution.

1. Edit the object style:

    - Turn off Size and Position.

    - Add "auto-fit" to the Fitting Options

2. Run the below script which will

    (a) set the width of the last column of each table (only if it contains a graphic cell), and

    (b) apply the "Table Graphic" object style to each graphic cell in the last column of each table.

You can try it out on the attached sample .indd doc. Let me know how that goes.

var myObjectStyleName = 'Table Graphic',
    lastColumnWidth = '3.7787 in';


function main() {

    var doc = app.activeDocument,
        tables = doc.stories.everyItem().tables.everyItem().getElements(),
        myObjectStyle = doc.objectStyles.itemByName(myObjectStyleName);

    if (!myObjectStyle.isValid) {
        alert('Could not find object style "' + myObjectStyleName + '"');
        return;
    }

    for (var i = 0; i < tables.length; i++) {

        var lastColumn = tables[i].columns.item(-1);

        cellsLoop:
        for (var j = 0, needsSizing = true; j < lastColumn.cells.length; j++) {

            var cell = lastColumn.cells[j];

            if (cell.cellType !== CellTypeEnum.GRAPHIC_TYPE_CELL)
                continue cellsLoop;

            if (needsSizing) {
                lastColumn.width = lastColumnWidth;
                needsSizing = false;
            }

            cell.contents.applyObjectStyle(myObjectStyle, true, true);

        }
    }

};

app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Size Last Column Graphics');
