BUG: to_html misses truncation indicators (...) when index=False

[jorisvandenbossche]

When the html output is truncated (by using mmax_rows=..), you get ... to indicate this, but not when using index=False:

df = pd.DataFrame(np.random.randn(5,2))
df.to_html(max_rows=4, index=False)

to_html misses truncation indicators (...) when index=False

and when index=True and max_rows=1 which is inconsistent with max_cols=1 behavior:

Reproducible code sample to use as test case:

Code Sample

np.random.seed(seed=0)
df = pd.DataFrame(np.random.randn(5,2))
df.to_html(max_rows=4, index=False)
