Select a textframe or a insertionpoint, and run it:

// Create a tbale whith specific number of row and column
if(app.documents.length !== 0 && app.selection[0].hasOwnProperty(“insertionPoints”)){
app.selection[0].tables.add(LocationOptions.AFTER, app.selection[0].insertionPoints[0], {
bodyRowCount: 8,
columnCount: 6,
footerRowCount: 0,
headerRowCount: 1
})
}

Try this:

app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, “Image Fitting Script”);
function main() {
// Capture the current selections in array
var mySelections = app.selection;
for (var i = 0; i < mySelections.length; i++) {
var myObject = mySelections[i];
if (myObject instanceof TextFrame) {
var allRtg = myObject.rectangles.everyItem().getElements();
for (var j = 0; j < allRtg.length; j++) {
var theRtg = allRtg[j];
try {
theRtg.fit(FitOptions.contentToFrame);
theRtg.fit(FitOptions.proportionally);
theRtg.fit(FitOptions.centerContent);
theRtg.fit(FitOptions.frameToContent);
} catch (e) {}
}
}
}
}
