DevExtreme React - Column and Row Indexes

The following indexes can be used in methods and callback functions:

  • Initial Column Index (or simply Column Index)
    Equals the column's index in the columns array.

  • Visible Column Index
    Depends on the column's current location in the TreeList and changes dynamically when columns are reordered.

    Do not confuse the visible column index with the index specified using the column.visibleIndex option. The latter is used in column reordering.

  • Row Index
    Starts from 0 and increases by 1 per row.
