If I'm understanding you correctly, you mean that your column names might be
different, like this?
[
{ colA: "valA", colB: "valB" },
{ colA: "valA", colC: "valC" },
{ colA: "valA", colD: "valD" },
]
If so, logic suggests that you would have to normalise the ArrayCollection
before providing it as a dataProvider, like this (whitespace added for
readability):
[
{ colA: "valA", colB: "valB", colC: "", colD: "" },
{ colA: "valA", colB: "", colC: "valC", colD: "" },
{ colA: "valA", colB: "", colC: "", colD: "valD" },
]
Then you can skip declaring and adding DataGridColumns seperately and just
feed the ArrayCollection to the dataProvider.
Hope this helps.
