When I upgraded my sapui5 version to 1.120.12 the tinymce table columns resize is not working anymore.
This the setting I have use:
window.tinymce.init({
selector: '#mainApp---test--myContainer',
inline: true,
table_resize_bars: true,
plugins: [ "table"],
});
the resize still working in sapuit version 1.115.1 the issue was introduce with 1.116. I have googled apparently this is not a known issue.
