Kako raditi s tablicama u Python

Aspose.Slides FOSS for Python supports creating tables on slides with configurable column widths and row heights. This guide shows how to add a table, populate it with data, and apply basic text formatting to cells.

Vodič korak po korak

Korak 1: Instalirajte paket 

pip install aspose-slides-foss

Korak 2: Stvorite ili otvorite prezentaciju 

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    # ... add table ...
    prs.save("table.pptx", SaveFormat.PPTX)

Korak 3: Definirajte širine stupaca i visine redaka

Tablice zahtijevaju eksplicitne širine stupaca i visine redaka u točkama (1 točka = 1/72 inča). Standardni slajd je širok 720 točaka i visok 540 točaka.

col_widths = [200.0, 150.0, 150.0]   # 3 columns: 200pt + 150pt + 150pt
row_heights = [45.0, 40.0, 40.0]     # 3 rows: 45pt header + 40pt data rows

Korak 4: Dodajte tablicu

slide.shapes.add_table(x, y, col_widths, row_heights) stvara tablicu na poziciji (x, y):

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]

    col_widths = [200.0, 150.0, 150.0]
    row_heights = [45.0, 40.0, 40.0]
    table = slide.shapes.add_table(50, 100, col_widths, row_heights)

    prs.save("table.pptx", SaveFormat.PPTX)

Korak 5: Postavite tekst u ćeliju

Pristupite ćelijama putem table.rows[row_index][col_index] i dodijelite tekst putem .text_frame.text:

import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]

    col_widths = [200.0, 150.0, 150.0]
    row_heights = [45.0, 40.0, 40.0]
    table = slide.shapes.add_table(50, 100, col_widths, row_heights)

    # Header row (row 0)
    headers = ["Product", "Units Sold", "Revenue"]
    for col, header in enumerate(headers):
        table.rows[0][col].text_frame.text = header

    # Data rows
    data = [
        ["Widget A", "1,200", "$24,000"],
        ["Widget B", "850", "$17,000"],
    ]
    for row_idx, row_data in enumerate(data):
        for col, cell_text in enumerate(row_data):
            table.rows[row_idx + 1][col].text_frame.text = cell_text

    prs.save("sales-table.pptx", SaveFormat.PPTX)

Korak 6: Formatirajte tekst zaglavlja ćelije

Primijenite podebljano formatiranje na zaglavlja ćelija koristeći PortionFormat:

from aspose.slides_foss import NullableBool, FillType
from aspose.slides_foss.drawing import Color

for col in range(len(headers)):
    cell = table.rows[0][col]
    portions = cell.text_frame.paragraphs[0].portions
    if portions:
        fmt = portions[0].portion_format
        fmt.font_bold = NullableBool.TRUE
        fmt.fill_format.fill_type = FillType.SOLID
        fmt.fill_format.solid_fill_color.color = Color.from_argb(255, 255, 255, 255)

Potpun radni primjer 

import aspose.slides_foss as slides
from aspose.slides_foss import NullableBool, FillType
from aspose.slides_foss.drawing import Color
from aspose.slides_foss.export import SaveFormat

data_rows = [
    ["North", "$1.2M", "+8%"],
    ["South", "$0.9M", "+4%"],
    ["East",  "$1.5M", "+12%"],
    ["West",  "$0.7M", "+2%"],
]
headers = ["Region", "Revenue", "Growth"]

with slides.Presentation() as prs:
    slide = prs.slides[0]

    col_widths = [180.0, 140.0, 120.0]
    row_heights = [45.0] + [38.0] * len(data_rows)

    table = slide.shapes.add_table(60, 80, col_widths, row_heights)

    # Header row
    for col, text in enumerate(headers):
        cell = table.rows[0][col]
        cell.text_frame.text = text
        if cell.text_frame.paragraphs and cell.text_frame.paragraphs[0].portions:
            fmt = cell.text_frame.paragraphs[0].portions[0].portion_format
            fmt.font_bold = NullableBool.TRUE

    # Data rows
    for row_idx, row_data in enumerate(data_rows):
        for col, text in enumerate(row_data):
            table.rows[row_idx + 1][col].text_frame.text = text

    prs.save("regional-revenue.pptx", SaveFormat.PPTX)

print("Saved regional-revenue.pptx")

Uobičajeni problemi i rješenja

IndexError prilikom pristupa table.rows[row][col]

Indeksi redaka i stupaca su bazirani na nuli. Ako ste definirali row_heights s 3 elementa, valjani indeksi redaka su 0, 1, 2.

Tekst u ćeliji ne pojavljuje se u spremljenoj datoteci

Uvijek dodjeljujte putem .text_frame.text, a ne putem .text izravno na objektu ćelije:

# Correct
table.rows[0][0].text_frame.text = "Header"

# Wrong: AttributeError or silent failure
table.rows[0][0].text = "Header"

Pozicija tablice je izvan slajda

Provjerite da x + sum(col_widths) <= 720 i y + sum(row_heights) <= 540 za standardni slajd.

Često postavljana pitanja

Mogu li spojiti ćelije tablice?

Spajanje ćelija nije podržano u ovoj ediciji.

Mogu li primijeniti pozadinsku boju na cijelu tablicu?

Primijenite formatiranje ispune na svaku pojedinu ćeliju:

for row_idx in range(len(table.rows)):
    for col_idx in range(len(table.rows[row_idx])):
        cell = table.rows[row_idx][col_idx]
        cell.fill_format.fill_type = FillType.SOLID
        cell.fill_format.solid_fill_color.color = Color.from_argb(255, 240, 248, 255)

Mogu li postaviti stilove rubova ćelija?

Svojstva rubova ćelije dostupna su putem table.rows[row][col].border_* svojstava. Pogledajte referencu API-ja za potpuni popis atributa formata rubova.
