boluor opened a new pull request, #3810:
URL: https://github.com/apache/doris-website/pull/3810
## Summary
Doc page (4.x): \`scalar-functions/string-functions/trim.md\` (EN).
The 2-arg trim example claimed:
\`\`\`sql
SELECT trim('ababccaab', 'ab') str;
\`\`\`
\`\`\`
| str |
| ababcca |
\`\`\`
On Apache Doris 4.1.1 the cluster returns \`cca\`, not \`ababcca\`.
\`trim(<str>, <rhs>)\` strips \`<rhs>\` from BOTH ends and repeats until
neither end starts/ends with \`<rhs>\`:
\`\`\`
'ababccaab' -> peel 'ab' from front: 'abccaab' -> peel 'ab' again: 'ccaab'
(front stops)
'ccaab' -> peel 'ab' from back: 'cca' (back stops)
final: 'cca'
\`\`\`
The ZH counterpart already shows \`cca\`. Update EN's expected output and
add a one-line intro that calls out the \"both ends, repeatedly\" semantics so
the result no longer looks surprising.
## Verification
\`\`\`
mysql> SELECT trim('ababccaab', 'ab') str;
+------+
| str |
+------+
| cca |
+------+
\`\`\`
## Test plan
- [x] Run on a 4.1.1 cluster — returns \`cca\`.
- [x] Result-table widths updated to fit the shorter value.
- [x] No other change.
