Even though I copy him and already define the Cell class, I still get an error

error CS0103: The name `colIndex' does not exist in the current context

for(int rowIndex = 0; rowIndex < sheet.GetLength(0); rowIndex++)
> {
> for(int colIndex = 0; colIndex < sheet.GetLength(1); colIndex++);
> {
> sheet[rowIndex, colIndex] = new Cell();
> }
> }

I wouldn't mind knowing what the heck is up

Try removing the ; after for(int colIndex = 0; colIndex < sheet.GetLength(1); colIndex++); to change it to for(int colIndex = 0; colIndex < sheet.GetLength(1); colIndex++)

for(int colIndex = 0; colIndex < sheet.GetLength(1); colIndex++);
{
    sheet[rowIndex, colIndex] = new Cell();
}

is equivalent to 

for(int colIndex = 0; colIndex < sheet.GetLength(1); colIndex++)
{
    // This code block runs for each pass of the for loop
}
{
    // This code block runs after the for loop ends
    sheet[rowIndex, colIndex] = new Cell();
}

Since sheet[rowIndex, colIndex] = new Cell(); is no longer in the for block, colIndex is no longer defined.
