The issue:
I have a dynamically built PPTX using Slides.net 18.3.
There’s only 1 Slide, which has an ITable, also built dynamically.
After being built, the ITable is too wide for the slide, so here’s what I do to “fix” the situation:
- I Clone a copy of the Original Slide (now there is the “Original” and a Clone). Both have ITables which are too wide.
- For the Original Slide - All of the ITable.Columns that are outside of the slide boundaries, I remove from the ITable starting from the far right, like this:
while (_table.width > slideWidth)
{
var index = _table.Columns.Count - 1;
addIndexToList(index);
_table.Columns.Remove(index, true);
}
- For each column which is removed, I save it’s respective Index to a List, as shown above.
- On the Cloned slide, I remove all of Columns EXCEPT those with the indexes from above.
The problems:
-
The Indexes are NOT a true index due to merged cells. It isn’t reliable. If I happen to remove a Column which has merged cells somewhere within its respective Rows, the Column count could decrease by something other than 1.
-
There’s no way to ensure the correct Columns are removed from the Cloned ITable without peeking at the Column data, which is a poor way to work (the Column text, for example, could be the same for several Columns).
-
There is no such thing as a ColumnID (as there is for a SlideID). If there was, all of the above would be simple.
-
You cannot “Clone” Columns from one ITable to another (which is why I have to remove Columns from the Cloned ITable and not just add the Original Columns to the Clone).
Suggestions mighty appreciated. Hope this made sense.
