I'm facing a problem with birt report , in the first column i have an image to display , when exporting to excel i see that there is a lot of merged cell together : see the picture below
NB:when exporting to excel i'm using an emitter
options = new EXCELRenderOption();
options.setOutputFormat("xls");
options.setOption(IRenderOption.EMITTER_ID, "org.eclipse.birt.report.engine.emitter.nativexls");
any help how to fix this please?
