When you create tables you must assign to each table a different number, from your script i see that you just assign "1" to all tables, well the tt cmd must be like that

PHP код:

COMMAND:tt(playerid, params[])
{
     if(GetPVarInt(playerid,"ontable") == 0) return SendClientMessage(playerid, -1 , "You are not in any table");
    new iText[ 128 ];
    if(sscanf(params, "s", iText)) return SCP(playerid, "[msg]");
    format(iStr, sizeof(iStr),"(( [TABLE] %s: %s ))", RPName(playerid), iText);
    for(new i, j=GetPlayerPoolSize(); i<j; i++)
    {
        if(GetPVarInt(i,"ontable") == GetPVarInt(playerid,"ontable"))
        {
            SendClientMessage(i, 0x216B98FF, iStr);
        }
    }
} 


and if you don't know how to do the rest post creating tables code
