dynamic array.

This is my code that fails to compile.

void ex1()
{
	alias the_row = string[];
	alias the_table = the_row[];
	
	File inFile = File("account.txt", "r");
	while (!inFile.eof())
	{
		string row_in = chomp(inFile.readln());
		string[] row_out = split(row_in,"\t");
		the_table ~= row_out; //Error: string[][] is not an lvalue
	}
	writeln(the_table.length); // Error: string[][] is not an 
expression
}

Welcome to D :-)


 	alias the_row = string[];
 	alias the_table = the_row[];

Here you are defining two types (and in D idiomatically types are 
written in CamelCase, so TheRow and TheTable).


 	File inFile = File("account.txt", "r");

This is enough:

auto inFile = File("account.txt", "r");


 	while (!inFile.eof())
 	{
 		string row_in = chomp(inFile.readln());

This should be better (untested):

foreach (rawLine; inFile.byLine) {
     auto row = rawLine.chomp.idup.split("\t");


 		the_table ~= row_out; //Error: string[][] is not an lvalue

theTable is not a variable, it's a type, so you need to define it 
like this:

string[][] table;
