Python使用tabulate包生成表格右列数据过长显示异常如何解决

• 方案1：使用maxcolwidths参数直接限制列宽
  这是最简单的处理方式，调用tabulate时直接指定各列的最大宽度，超出宽度的内容会自动换行，避免表格整体变形：

from tabulate import tabulate

# 此处替换为你自己的表格数据
data = [
    ["TRILOSTANE", "Plaque, Amyloid , Eye Pain , Sacroiliitis , Cognitive Dysfunction , Drug-Related Side Effects and Adverse Reactions , Non-alcoholic Fatty Liver Disease , OVARIAN DYSGENESIS 1 , Abortion, Spontaneous , Squamous Cell Carcinoma of Head and Neck , Acromegaly , ACTH Syndrome, Ectopic , Adenocarcinoma , Adenoma , Adrenal Cortex Diseases , Adrenal Gland Neoplasms , Adrenal Hyperplasia, Congenital , Alcoholism , Alzheimer Disease , Amenorrhea , Amnesia , Amyloidosis , Angina Pectoris , Angina, Unstable , Hypoxia , Anuria , Anxiety Disorders , Aortic Stenosis, Subvalvular , Arrhythmias, Cardiac , Arterial Occlusive Diseases , Asphyxia Neonatorum , Asthma , Astrocytoma , Atrial Fibrillation , Autistic Disorder , Mental Disorders , Behcet Syndrome , Bipolar Disorder , Urinary Bladder Neoplasms , Body Weight , Bone Diseases, Metabolic , Bone Neoplasms , Bradycardia , Brain Diseases , Brain Edema , Breast Neoplasms , Burns , Cachexia , Calcinosis , Carcinoma , Carcinoma, Non-Small-Cell Lung , Carcinoma, Renal Cell"]
]

# 可按需调整各列的最大宽度数值，示例中第一列最大宽30，第二列最大宽80
print(tabulate(data, tablefmt="grid", maxcolwidths=[30, 80]))

• 方案2：配合textwrap模块自定义换行规则
  如果需要更灵活的换行控制，可以提前用textwrap对长文本做拆分处理，再传入tabulate生成表格：

from tabulate import tabulate
import textwrap

# 对长文本列做换行处理，每行最多80个字符，宽度可自定义
wrapped_long_col = textwrap.fill(data[0][1], width=80)
processed_data = [[data[0][0], wrapped_long_col]]

print(tabulate(processed_data, tablefmt="grid"))

• 方案3：输出到文件避免终端截断
  如果需要保留完整长行不换行，可以把生成的表格输出到markdown、html等格式的文件中，不会受到终端宽度的限制：

from tabulate import tabulate

with open("output_table.md", "w", encoding="utf-8") as f:
    f.write(tabulate(data, tablefmt="pipe"))
