dealing with a table whose column widths and border widths are defined in parallel arrays. i want to sum the width of a cell which spans multiple columns. this means X until X + colSpan column widths and X + 1 until X + colSpan - 1 border widths. I want to inset the IntRange I already have for columnSpanIndicies so that I can use it on the border widths without referencing the original input values or manually doing math on both ends (which are both error-prone and do not represent the relationship of column width indices to border widths).
