You can use the string.fromNum() method along with the Table("TableName")[row][col] format to compose the message being sent with serversend().

But how do you want to send values from the table to the client? You could send the value from the last row every time a row is added (in the same event/code that is adding the rows), like this:

serversend(server,string.fromNum(Table("entry sink time")[Table("entry sink time").numRows][1]));

Or you could send the entire table of numbers in one big "blob" after the model has finished running, like this:

string message = "";
Table table = Table("entry sink time");
int tableNumRows = table.numRows;

for (int row = 1; row <= tableNumRows-1; row++) {
   message += string.fromNum(table[row][1]) + ", ";
}
message += string.fromNum(table[tableNumRows][1]);

serversend(server, message);

But you most likely want to use some combination of string.fromNum() and Table()[row][col].
