Re: tdf#50916 : Calc : Dynamic column container

Hi All It has been quite a while since I worked on this bug. Lately I have been thinking about "a better way to handle row formattings". In the current setting, if someone formats whole row, it is required that we have all columns from 0 to MAXCOL allocated, which is bad when MAXCOL is a big numbe

Re: tdf#50916 : Calc : Dynamic column container

So, I'm gonna reply to Eike's post, but my reply is not in response to Eike's, but just a general idea I have on this subject. I had already discussed this with Markus before he posted his, and his post also reflects my view on this in general. First off, allowing dynamic growth of column contain
