Bash端末で正しい列をどのように設定しますか？

私のコード出力に適した列を定義しようとしています。問題は、列の要素の1つが空の場合、または文字制限を超えると、後続の列要素が置き換えられることです。

VULDB-ID        LEVEL   CVE             TITLE

122215          LOW     CVE-2015-9261   BusyBox up to 1.27.1 ZIP File decompress_gunzip.c null pointer dereference
119934          MEDIUM  CVE-2018-1000517        BusyBox wget memory corruption
119917          MEDIUM  CVE-2018-1000500        BusyBox SSL Certificate Validator certificate validation
96755           LOW     CVE-2016-2147   BusyBox up to 1.24.x DHCP Client integer overflow
94808           MEDIUM  null    BusyBox up to 1.23.1/1.4.x cmdline arp_main IFNAME memory corruption
93993           MEDIUM  CVE-2016-6301   BusyBox NTP Packet networking/ntpd.c recv_and_process_client_pkt resource management

私はテーブルを出力するために次のコードを使用しています

title=$(jq -r .entry.title result.json 2>/dev/null)
cve=$(jq -r .source.cve.id result.json 2>/dev/null)
id=$(jq -r .entry.id result.json 2>/dev/null)
level=$(jq -r .vulnerability.risk.name result.json 1> level.tmp 2> /dev/null)    

paste <(tput smul; printf %s"VULDB-ID"; tput rmul) <(tput smul; printf %s"LEVEL"; tput rmul) <(tput smul; printf %s"CVE"; tput rmul;) <(echo) <(tput smul; printf %s"TITLE"; tput rmul)
paste <(echo "$id") <(echo) <(cat level.tmp) <(echo "$cve") <(echo "$title") | column -t -s "\"" -L

データは次のjsonファイルから抽出されます。

今私の質問は

1. 列を直接定義する必要がありますか？では、どうすればよいですか？
2. 欠けている熱をきれいに印刷するより簡単でエレガントな方法はありますか？
