the complete table. please guide me on the following

1. how do i print whole table
2. how you are writing data to ".tbl" file
3. how you are sending from ".tbl" file
     
function handle.TableNew(asset, x)

    print("*****-->Entering handle.TableNew*****************")
    print("***********************************************")
    table.foreach(x, print)
    print("***********************************************")
   
    asset=x.asset--Need to work with assetname
    local path = upath.concat(asset, x.path)
    local table_id = get_table_id (path, x.storage, x.columns)
    local P = POLICIES[x.policy or 'default']
    if not P then return errnum 'BAD_PARAMETER', "no such policy" end

    -- check whether the table is created or reused from existing
    local t = TABLES[table_id]
    if t then
     print("****** Table Already exists***********")
        -- table already exists, if it is a destination table, it is incorrect
        -- to retrieve it from a this method
        if t.src_table then return errnum 'BAD_PARAMETER', "cannot create or retrieve "..table_id.." because it is a destination table." end
        if x.purge then
            local ok, msg = M.close_table(nil, table_id)
            if not ok then return errnum 'BAD_PARAMETER', msg end
            t = nil
        elseif not match_columns(t, x.columns) then
            return errnum 'BAD_PARAMETER', "cannot reuse "..table_id..": columns does not match"
        end
    end

    -- create table if not exists or purged
    if not t then
        print("****** Creating New Table***********")
        log('DATAMGR', 'DEBUG', "Create new table %s", table_id)
        local sdb, errmsg = stagedb(table_id, x.columns)
        if not sdb then return errnum 'UNSPECIFIED_ERROR', errmsg end
        t = { id=table_id, path=path, sdb=sdb }
    else log('DATAMGR', 'DEBUG', "Retrieving existing table %s", table_id) end

    t.send_policy=P
    P.tables[table_id] = t
    TABLES[table_id] = t
   
   
    print("*******Created table*****")
    print("***********************************************")
    for k , v in pairs(t.sdb) do
        print(tostring(k).."  "..tostring(v))
    end
    print("***********************************************")
   
    return 0, table_id
end
